[libvirt-glib][PATCH 2/2] python: Introduce support for python3

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Just like libvirt itself is able to work with both major version
of python, libvirt-glib should do the same. Even the code I'm
introducing here is copied from there (and changed slightly to
reflect project name).
