Bind's handling of lame nameservers

[Mark Andrews]

We tried to check aa for just this reason but there are to many
broken authoritative servers which just don't set "aa=1" on all the
servers for the zone that we had to back the code change out.

I would just use a server clause to mark nameserver as bogus.
