[libvirt] [RFC PATCH 1/2] spec: Remove capabilities cache during %post install

[John Ferlan]

https://bugzilla.redhat.com/show_bug.cgi?id=1195882

Force re-reading of the capabilities cache upon new installations.

Since re-reading of the capabilities is based on the 'ctime' of either
the QEMU binary or if the new libvirtd is greater than what created the
cache file, it's possible that depending on the order of installations
that a later date created "backported" libvirtd could create the cache
file while followup installation of a mainline release that had an
earlier creation date wouldn't cause the cache to be updated. This
results in the possibility that (a) feature(s) in the mainstream
release wouldn't be available unless someone delete the cache by hand.
