We should have the 'make  install' rule create that directory

I think we should just handle this a little differently.

Basically don't do any setup in the RPM of the storage pool config, merely
have /var/lib/libvirt/images created - this is already done in fact.

Then if virt-install, or virt-manager run and find no configured storage
pools at all on a host at time of VM creation, they should simply create
the default one pointing at /var/lib/libvirt/images/.
