[RFC] helpers: specify Python 2.7, not just any python2

[Brian Norris]

The 'argparse' package is new in 2.7. Some installations (e.g., RHEL 6)
still have a default python2 of Python 2.6, but can optionally install
2.7.

I think this is safe. FWIW I've tested it on RHEL 6 and a couple of different
Ubuntu systems.
