epel9 template needed for missing python2

[nkadel]

RHEL 9 does not include python2. An updated template that leaves python2 off entiely, or updating the epel templates to enable it only as appropriate, is needed to avoid having to hand-edit newly generated spec files.

See my submitted pull request at #289 . python2 needs to be turned off by default, in favor of python3.
