[libvirt] [PATCH v2 19/19] spec: Install udev helper/rule more cleanly

[Michal Privoznik]

In the previous patch we've introduced a configure check to see
whether there's sufficiently new udev present in the system. I
mean, the rule we've introduced relies on udev patches that were
introduced in the 232 release. This one is not that widely
present yet, therefore our spec file should count on that.
