Laine Stump b449603192 network: eliminate code that uses default iptables chains
The network driver has put all its rules into private chains (created
by libvirt) since commit 7431b3eb9a, which was included in
libvirt-5.1.0. When the conversion was made, code was included that
would attempt to delete existing rules in the default chains, to make
it possible to upgrade libvirt without restarting the host OS.

Almost 3 years has passed, and it is doubtful that anyone will be
attempting to upgrade directly from a pre-5.1.0 libvirt to something
as new as 8.0.0 (possibly with the exception of upgrading the entire
OS to a new release, which would include also rebooting), so it is now
safe to remove this code.
