www/dansguardian*: relinquishing maintainership

[Freddie Cash]

As we no longer run Squid/Dansguardian on FreeBSD boxes at work, and I don't
have time to test it after work, it's with regret that I must relinquish
maintainership of the two dansguardian ports:
  www/dansguardian
  www/dansguardian-devel

I'll try to update it to the latest stable release, but I can't do more than
compile testing at this point.
