[PATCH 2/2] nfstest: fix another RHEL 8-ism

[Scott Mayhew <smayhew@redhat.com>]

RHEL 8 doesn't have the python-unversioned-command package.  So we'll
install python-unversioned-command on RHEL/CentOS 9 and higher, and on
RHEL/CentOS 8 and lower we'll set up the /usr/bin/python symlink via
the 'alternatives' command.

I'm not doing any special checking on Fedora, which has had the
python-unversioned-command package since F29.  I'm assuming anyone using
kdevops to run nfstest on Fedora is going to be using a much more recent
version.
