I don't think we can generalize this patch for other hypervisors. For example
lxc don't create "%{_localstatedir}/lib/libvirt/lxc/" in runtime thus this
directory need to be installed.

I also give this patch more thought and think we can fix issue differently.

- use %ghost directive just like for run dir so that we cleanup on uninstall additionally
- install dir as root:root and don't change owner at runtime. Why do we need 
to make lib and cache group:owner qemu:qemu in the first place? Looks like
we only store qemu caps cache and domain screenshots in cache and both files
are created by daemon itself. And lib dir only have directories which 
in turn created by daemon too:

[localhost]# ls dir
boot  dnsmasq  filesystems  images  libxl  lockd  lxc  network  qemu  sanlock  uml  xen
