file: Correctly check for remoteness for speed tradeoffs

When the thumbnailing and/or item counting preference is 'local-only',
we need to know if a file is local or remote, and for this we use the
nautilus_file_is_local() method.

However, ever since the port from gnome-vfs to GIO, this method relies
on g_file_is_native() instead of gnome_vfs_uri_is_local(), which are
not the same thing. Quoting the GIO docs:

> A native file is one expressed in the platform-native filename
> format, e.g. "C:\Windows" or "/usr/bin/". This does not mean the
> file is local, as it might be on a locally mounted remote filesystem.

So, nautilus_file_is_local() is no longer telling us the truth. This
means we may show thumbnails or item counts for natively-mounted remote
locations when we are not supposed to.

Instead, let's use the nautilus_file_is_remote() method, which relies
on the G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE attribute (which was not
implemented at the time of the GIO port).
