Cannot add virtualization-host formula on a SLES 12 system - missing python3-libvirt-python package

[srinidhibs]

On my Uyuni 2021.03 server, I've added a SLES 12 SP5 system that is hosting a few VMs on KVM. When I enable the virtualization-host formula for this host, the highstate can never be installed:

    Function: pkg.installed
        Name: virthost_packages
      Result: false

On SLES 12 SP5, there is no package called python3-libvirt-python, rather it has the python-libvirt-python package. I believe, the issue is in the following line where the package name is hardcoded rather than being put in a conditional:

salt-formulas/virtualization-host-formula/virtualization-host/map.jinja

Line 24 in 9e0b723

'python3-libvirt-python',

If I move this package to the condition at the top of the file, then I'm able to apply the highstate on the SLES 12 SP5 host machine. But I do not know if this is the right way to handle this:
