[gtk+/gdk-backend-wayland] Create and attach buffer at process_updates time



commit 833f0ee740e052490fbfe037687531bd175f101c
Author: Kristian Høgsberg <krh bitplanet net>

    Create and attach buffer at process_updates time
    
    This way we don't try to show the buffer until we've handle the initial
    expose.
