CI: Test 2.4.x in qemu-test-repo-vm.sh, quick mode

The qemu-test-repo-vm.sh script tests installs ZFS from different
repos.  Have it test from the new 2.4.x repos as well.

Also add a checkbox to run in "lookup mode".  This just does a
quick lookup to see what version is installed in each repo.  It does
not do a test install and module load.  It only takes 3min to run vs
over an hour for the full version.
