Be explicit about using Python 2.x

We'd like to migrate to Python 3.x for our tests and scripts. But
that's a lot of work.

But distributions would like us to be explicit about the version
of python that our tests and scripts use. See:

https://taskotron.fedoraproject.org/artifacts/all/ec52504e-9e9f-11e7-86b2-525400817a8f/task_output/output.log

and

https://fedoraproject.org/wiki/Packaging:Python#Dependencies

Closes #7725
