[Groff] Links to CSTR in roff(7)

[Jan Stary]

The roff(7) contains broken links.
Namely, http://cm.bell-labs.com doesn't even exist any more.

The archive of the Bell Labs Journal and the technical reports
seem to be available at https://www.alcatel-lucent.com/bell-labs-journals
but I didn't go through the indiviudual references. (I did once,
to download them, but that was before I read roff(7) now.)

The Ossana paper is available at troff.org,
but the other papers are linked (by troff itself)
to the nonexistent http://cm.bell-labs.com .
