xenbridge is only enabled if OldSeparateBridgeInitd is set, which it is
not for a modern Xen install so I think this is a red-herring.

The host networking is configured by the function nodhcp in
ts-xen-install.

Per our previous conversations once the L1 guest is installed you can
mostly treat it as a if it were an L0 host wrt configuring it. In other
words there should be no need for a separate setup_l1_bridge function,
just some minor modifications to ts-xen-install.
