Similar to other interface types, we can detect a bridge by the
presense of it's bridge_ports attribute rather than solely relying on
the "vmbr" ifname prefix heuristic.

For OVS bridges we need to examine the OVS type instead.

The check needs to be moved up since other prefixes could
theoretically be included in a bridge name and then would otherwise
get picked up wrongly.
