[gentoo-python] [PATCH python-ebuilds] python2.7: first ebuild converted to python-utils-r1.

["Michał Górny" <mgorny@gentoo.org>]

Please review these changes. I will send a detailed note about
the particular changes I've made in a reply to this mail.

The general changes are:

- clean up, update, getting rid of python.eclass implicity,

- the compiled modules are now part of the package (as with other
  python-r1 suite ebuilds),

- an additional 'epython' module is installed which could be used to
  quickly get the correct 'EPYTHON' value for the current Python
  implementation (it will be used in python-exec's .py support).
