Make clipboard tests run installed

Use dedicated data files, and install them.
As usual, to run the test binary by hand, you
will need to set G_TEST_SRCDIR.

+ * GtkWidgetClass:
+ * @parent_class: The object class structure needs to be the first
+ *   element in the widget class structure in order for the class mechanism
+ *   to work correctly. This allows a GtkWidgetClass pointer to be cast to
+ *   a GObjectClass pointer.
+ * @show: Signal emitted when widget is shown
+ * @hide: Signal emitted when widget is hidden.
+ * @map: Signal emitted when widget is going to be mapped, that is
+ *   when the widget is visible (which is controlled with
+ *   gtk_widget_set_visible()) and all its parents up to the toplevel
+ *   widget are also visible.
+ * @unmap: Signal emitted when widget is going to be unmapped, which
+ *   means that either it or any of its parents up to the toplevel
+ *   widget have been set as hidden.
+ * @realize: Signal emitted when widget is associated with a
+ *   #GdkSurface, which means that gtk_widget_realize() has been called or
+ *   the widget has been mapped (that is, it is going to be drawn).
+ * @unrealize: Signal emitted when the GdkSurface associated with
+ *   widget is destroyed, which means that gtk_widget_unrealize() has
+ *   been called or the widget has been unmapped (that is, it is going
+ *   to be hidden).
+ * @root: Called when the widget gets added to a #GtkRoot widget. Must chain up
+ * @unroot: Called when the widget is about to be removed from its #GtkRoot widget. Must chain up
+ * @size_allocate: Called to set the allocation, if the widget does
+ *   not have a layout manager.
+ * @state_flags_changed: Signal emitted when the widget state changes,
+ *   see gtk_widget_get_state_flags().
+ * @direction_changed: Signal emitted when the text direction of a
+ *   widget changes.
+ * @get_request_mode: Called to get the request mode, if the widget
+ *   does not have a layout manager.
+ *   This allows a widget to tell its parent container whether
+ *   it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
+ *   %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
+ *   %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH means the widget prefers to have
+ *   #GtkWidgetClass.measure() called first to get the default width (passing
+ *   a for_size of -1), then again to get the height for said default width.
+ *   %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
+ *   width-for-height geometry management for said widget and is the
+ *   default return.
+ *   It’s important to note that any widget
+ *   which trades height-for-width or width-for-height must respond properly
+ *   to a for_size value >= -1 passed to #GtkWidgetClass.measure, for both
+ *   possible orientations.
+ * @measure: Called to obtain the minimum and natural size of the widget,
+ *   if the widget does not have a layout manager.
+ *   Depending on the orientation parameter, the passed for_size can be
+ *   interpreted as width or height. A widget will never be allocated less
+ *   than its minimum size.
+ * @mnemonic_activate: Activates the @widget if @group_cycling is
+ *   %FALSE, and just grabs the focus if @group_cycling is %TRUE.
+ * @grab_focus: Causes @widget to have the keyboard focus for the
+ *   #GtkWindow it’s inside.
+ * @focus: Vfunc for gtk_widget_child_focus()
+ * @set_focus_child: Sets the focused child of a widget. Must chain up
+ * @move_focus: Signal emitted when a change of focus is requested
+ * @keynav_failed: Signal emitted if keyboard navigation fails.
+ * @query_tooltip: Signal emitted when “has-tooltip” is %TRUE and the
+ *   hover timeout has expired with the cursor hovering “above”
+ *   widget; or emitted when widget got focus in keyboard mode.
+ * @compute_expand: Computes whether a container should give this
+ *   widget extra space when possible.
+ * @css_changed: Vfunc called when the CSS used by widget was changed. Widgets
+ *   should then discard their caches that depend on CSS and queue resizes or
+ *   redraws accordingly. The default implementation will take care of this for
+ *   all the default CSS properties, so implementations must chain up.
+ * @system_setting_changed: Emitted when a system setting was changed. Must chain up.
+ * @snapshot: Vfunc called when a new snapshot of the widget has to be taken.
+ * @contains: Vfunc for gtk_widget_contains().
