gdbusinterfaceskeleton: Remove an unnecessary helper struct member

The `GDBusInterfaceSkeleton` is already stored as the source object of
the `GTask` here, with a strong reference.

Storing it again in the task’s data struct is redundant, and makes it
look like the `GDBusInterfaceSkeleton` is being used without holding a
strong reference. (There’s not actually a bug there though: the strong
reference from the `GTask` outlives the data struct, so is sufficient.)

Remove the unnecessary helper struct member to clarify the code a bit.
