ci: Add a few more drivers to the cross builds

This is mostly to get additional -Werror coverage to avoid introducing
unforced ILP32 or big-endian errors. i386 adds lavapipe, r600, nouveau,
zink, and all the classic drivers. ppc64le adds lavapipe and zink, and
also adds -Werror for symmetry with the other cross builds. s390x also
adds lavapipe and zink.
