[Piglit] [PATCH v2 5/7] Bumps python required version to 2.7

[Dylan Baker]

This change is in preparation for the next patch that replaces getopt
with argparse. Argparse is only available in python 2.7+ and 3.2+.

One concern with this change is the availability of Python 2.7 on
non-Linux platforms, however:
- OSX 10.8 ships with python 2.7.2
- OSX 10.7.4 ships with python 2.7.1
- 2.7.3 is available for windows

V2: - Splits this change from the next patch (Replaces getopt with
      argparse)
