chat: Remove gossip, GNOME 2 XMPP client with vanished upstream.

This used to be part of GNOME (I guess? never heard of it before), but
the last release was pushed to ftp.gnome.org over 10 years ago.

Despite this, the version in pkgsrc is not the most recent release.

Other vendors have packages named 'gossip' but they appear to be for a
different piece of software...

There's plenty of other XMPP clients in pkgsrc to try.

PKGREVISION=	56, last updated in 2006.
