data: Improve udev rule for unmanaging docker bridges

Docker supports creation of additional networks and these are named
br-something. These networks are used by docker-compose, for example.

While at it, restrict the match to ID_NET_DRIVER=bridge. Docker probably
also supports other network types, but the naming is different and this
rule won't match them anyway.
