--with-iptables-prefix was added to integrate with a proposed system for letting iptables know how to reload our rules. The idea was that we'd add our rules to a chain like libvirt-INPUT rather than INPUT, and there'd be a configuration file which would specify whether INPUT should include libvirt-INPUT. The proposed system wasn't accepted so, although there might be some other theoretical use for this, let's just remove it.
