Remove all remnants of python <2.7

[Perry E. Metzger]

Yesterday, Ryan pointed out in the course of a pull request that the
port in question still had support for python 2.5(!).

I'd like to propose that we should systematically remove all
references in Portfiles to any version of Python before 2.7. In the
case of ports that do not appear to support Python 2.7, we should
probably deprecate the port.

Thoughts?
