test: Use either wayland-info or weston-info

Merged Olivier Fourdan requested to merge ofourdan/xserver:xwayland-fix-xts-tests into master

weston-info has been deprecated for quite some time, whereas wayland-info may not be available yet.

So we use either, depending on what's actually available.

This is preventing new releases of Xwayland on recent distributions (e.g. Fedora 38), this is therefore a release blocker.
