waylandsink: Set external surfaces and their child objects to use our own event queue

This fixes weird freezes because of frame_redraw_callback() not being
called from the main thread when it should with weston's toy toolkit.

It's also safer to know that frame_redraw_callback() will always be
called from our display thread... Otherwise it could be called after
the sink has been destroyed for example.
