Add c2man, tool to generate documentation from C source code comments

Add with DEPRECATED but without EXPIRATION_DATE because it is not recommended
for use in new projects.  We still add this port because there is needed for
building GNU FriBidi from git snapshot.

+c2man is an obsolete and unmaintained documentation tool that extracts comments
+from C source code. Do not use this tool in new projects. The only reason for it
+to exist in FreeBSD ports is to allow building GNU FriBidi from a git snapshot.
