Use native-deb* targets for zloop workflow

The zloop workflow always requests an Ubuntu worker.  Since we
now have native Debian style packaging use these targets for
the zloop workflow.  This follows up on the work done in openzfs#14265.

Additionally, rollback to using the ubuntu-20.04 builder until
the ax_python_dev.m4 LegacyVersion build issue with 22.04 has
been resolved.
