Generally in NetBSD we've not automatically started service `b'
that service `a' depends upon.

However, in the specific case of ipnat and ipfilter we had prior art
(to rc.d), so those semantics were retained for this specific case.

Note that FreeBSD's use of our rc.d code retains *their* prior art
of "start dependent service x (e.g., rpcbind) if service y (e.g, mountd)"
needs it.

As mentioned above, our general policy is to not start up dependent
services.  ipnat is a special case (with prior art).
