Emmanuel Gil Peyrot f99e48ae6a wayland: use the advertised size in fullscreen 
When we receive the wl_shell_surface::configure event, it makes sense
to respect the aspect ratio of the video in windowed mode, but in
fullscreen it forces compositing and wastes resources (until atomic
modesetting is available everywhere and we can stop having
desynchronised planes).

Weston mitigates a resolution mismatch by creating black surfaces and
compositing them around the fullscreen surface, placed at the middle,
while GNOME puts it at the top-left and leaves the rest of the desktop
composited below, both of them producing a subpar experience.

Fixes #3021, #2657.
