Also, dnsmasq not required for NAT-ed networks.

And libvirt-0.9.3 doesn't have this dependency resp. works as I've
written above - no dnsmasq during compilation, no dnsmasq dependency later.
May be some of the patches in Changelog introduced this kind of
dependency? I've seen patches regarding return-codes from dnsmasq.
