waylandsink/waylandpool: call the start/stop methods of the parent class

start() makes sure that the minimum ammount of buffers requested is allocated.

stop() makes sure that buffers are actually destroyed and prevents
filling the file system when resizing the surface a lot, because the
wayland-shm-* files will stay on the file system as long as the wl_buffers
created out of them are alive.
