CI: Test build Lustre against ZFS

The Lustre filessytem calls a number of exported ZFS functions.  Do a
test build on the Almalinux runners to make sure we're not breaking
Lustre.  We do the Lustre build in parallel with the normal ZTS test
for efficiency, since ZTS isn't very CPU intensive. The full Lustre
build takes around 15min when run on its own.
