Issue

Some of the RPM packages' post-install or post-transaction scripts fail because
they explicitly run python2, even when only Python 3 versions of packages are
available.

Steps to Reproduce

1. install (upgrade) the packages

Actual behavior

• the freeipa-client post-install script fails with a visible error message
• the freeipa-server post-transaction script terminates early without actually running ipa-server-upgrade.

Expected behavior

The upgrade scripts do not error and do run the required programs.
