Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

net-mgmt/rancid, devel/cvs(2html,-syncmail): Fix recent cvs dependency

CVS is no longer in base on FreeBSD 10 and later, but it's still in
DragonFly's base, and the devel/cvs port doesn't even build on DF.  The
dependence on CVS was added to some ports recently, make sure that only
applies to FreeBSD.  Note the rancid approach where it further limits
it to FreeBSD 10+ is better than devel/cvs* where they pull in CVS
unconditionally on FreeBSD 8 and 9 where it's not needed.  The
unmaintained cvs-syncmail port was updated to be like rancid, but I
didn't make the same update to the maintained cvs2html port.

Support stage
Use shebangfix
Remove support for the nonexisting cvsnt
Add dependency on cvs
