add support for EL9 (RedHat, Rocky and AlmaLinux)

[sircubbi]

This PR will add support for EL9 and also include AlmaLinux in the process.

Please note that CI is currently failing (which I fixed in PR #181). I can rebase once that other PR got merged.

Haha - beat me to this one as well!

Does Alma have the same paths for FreeRADIUS as CentOS/RHEL/Rocky? I've not used Alma.

It actually does. Only difference between the different flavours are more or less the copyrighted artwork and logos from RedHat.

Have you had a look at #178? I think the same issue exists in EL9

Yes, I saw that. However it is not necessary in EL9, since bootstrap is not called there. Comparing the systemd-Unitfiles I see that ExecStartPre=-/bin/sh /etc/raddb/certs/bootstrap is no longer present on EL9, most likely related to this changelog-entry:

* Wed Mar 10 2021 Robbie Harwood <rharwood@redhat.com> - 3.0.21-11
- Disable automatic bootstrap

I just rolled out a new freeradius-configuration on Rocky9 yesterday and had no issues with this puppet module (except the missing guess for the version of the freeradius-package, which is fixed with this PR).

Go for gold

Thanks, rebase is done and the CI now actually goes green ;)
