Add travis build config

Enable builds on several python versions, and against several versions
of libvirt. Ideally we would build all the way back to 0.9.11, since
that is the min supported libvirt for python binding. It is not possible
to build this old libvirt version on modern distros though, so using
1.2.0 as the oldest for now.
