clone: handle python package names
clone: handle python package names

Our python packages are named differently on RHEL vs Ubuntu.

If running "clone" with a python-* package name, switch to the Debian
bare package name instead.

This allows us to run "rhcephpkg clone python-foo" in Jenkins (triggered
if we see "python-foo"'s patches branch change.)
