TorRelayGuide/NetBSD: set ORPort to 443 where that works out of the box

So far we used 443 where that works out of the box, you don't seem to like that:

443 is a more likely reachable port than 9001, what is your motivation for changing it to 9001, especially since you are recommending people to set a random port? ("TRY A DIFFERENT PORT" should be explained) on a non-exit (likely guard) relay?
