ci: Build weston 14.0.1 from source

There is a bug in Weston 10 that's causes instability when we don't have
wl_drm which isn't likely to get fixed in a point release.  Most of CI
is fine but the final patch in this MR causes AMD raven to kill weston
part-way through runs, destroying the run.  Just update weston to
14.0.1.
