This is exactly how we already treat nwfilters, which require
the same kind of care (aka nasty hacks) as the default network,
because in both cases the UUID is generated and written to
disk the first time libvirtd is started after installing the
corresponding subpackage.

After this patch, RPM will be aware of the fact that the
libvirt-daemon-config-network subpackage owns the default
network.
