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.
