Remove dns/nsd2 at maintainer's request:
This version of nsd is end of life since 2007 and unsupported.
See the details at http://nlnetlabs.nl/projects/nsd/nsd-v2.html.
The current version also contains a vulnerability. It is much
more sensible to move to a supported version (as available in
the port dns/nsd).
