I was a bit too focused on getting the YAML right to not realize
it is simpler to do:

QEMU_JOBS=all          # default, overwritable
QEMU_JOBS=system,fuzz  # only build those jobs
                       # can be set in fork UI config (see [2])
                       # can be set with git-push option (see below)
