packaging: use "--python python" for centos7 to avoid explicit "python2"

This is a partial backout of 92a51a45d44c.

We will need to be able to control whether package dependencies are python2 or
python3. Generally (at least in recent Fedora), the package prefix match the
name of the python executable ...  but CentOS 7 doesn't use the python2 prefix
in package name or alias for python-docutils yet, so just keep centos7 in the
unversioned "python" world.

Change the new (unused) buildrpm "--python3" option (introduced in
a6dcac6454c1) to "--python python3" to get a more generic method for explicit
control over whether we use python, python2 or python3.
