Jarrod Johnson 56fa13279e Explicitly indicate use of python2
RHEL8 will no longer tolerate implicit use of python.
For now relent to being python2, though ideally one day
it could be either.

Unfortunately, this means once code is ready for python3, we have to
probably implement build time changes for python3 enabled distros
to have different shebangs than python2 distros.
