build: improve rpm generation for distro backports

When building for an older distro, it's convenient to just
tell rpmbuild to define dist (for example, to .el6_0), rather
than also remembering to define rhel to 6.

* libvirt.spec.in: Guess %{rhel} based on %{dist}.
Based on an idea by Jiri Denemark.
