Move recipes to use Python 3 whenever possible

This patchset updates recipes to use Python 3 whenever possible. A few items cannot be moved at the moment for various reasons, here they are:

1) Smartpm package manager has not been ported to Python 3 and it is unlikely to happen:
https://github.com/smartpm/smart/issues/4
We need to look into alternatives such as yum or dnf (the 'next generation' fork of yum).

Consequently, rpm's python bindings (required by smartpm) stay at python 2 as well for now, even tough python 3 seems to be supported.

2) Scons build system is python 2 only, due to lack of resources.

3) createrepo recipe is using an upstream version from 2007, before createrepo was rewritten on top of yum's python modules.

We need to look into adding yum recipe which will allow updating createrepo to latest upstream. Also, libxml2 is currently a createrepo dependency, and so stays at Python 2 for now.

4) varous recipes that haven't been ported: kconfig-frontends, mklibs, opkg-utils, ltp, mc, parted, libepoxy, mesa, perf, rt-tests, webkitgtk.

5) LSB spec is implicitly requiring Python 2 (via requirement for '/usr/bin/python').

6) gobject introspection has been ported to Python 3 in release 1.48. I'll send this update separately, as a part of normal version update patches.

7) piglit has been ported to Python 3 as well in the latest upstream releases, Jussi Kukkonen should take care of it. I've added piglit's python dependencies in their Python 3 versions - python3-mako and python3-numpy, so that the task should be a little easier.

The following changes since commit c7e614c438706fb3ed7520b4990ebb3973366942:

useradd: Fix infinite build loop (2016-05-23 10:33:45 +0100)
