Olivier Fourdan 785e59060c xwayland: Fix infinite loop at startup 
Mutter recently added headless tests, and when running those tests the
Wayland compositor runs for a very short time.

Xwayland is spawned by the Wayland compositor and upon startup will
query the various Wayland protocol supported by the compositor.

To do so, it will do a roundtrip to the Wayland server waiting for
events it expects.

If the Wayland compositor terminates before Xwayland has got the replies
it expects, it will loop indefinitely calling `wl_display_roundtrip()`
continuously.

To avoid that issue, add a new `xwl_screen_roundtrip()` that checks for
the returned value from `wl_display_roundtrip()` and fails if it is
negative.
