Since libvirt uses cgroups for various aspects of guest tuning, we need to
make sure that the host is configured with them enabled out of the box.
The libcgroup maintainer has now provided a suitable default config that
mounts them all in /cgroup. So libvirt simply needs to depend on libcgroup
RPM, and turn on the 'cgconfig' initscript at install time if QEMU or LXC
is enabled.
