hghave: add cvsnt

cvsnt is a maintained commercial fork of cvs
https://en.wikipedia.org/wiki/CVSNT

It is possible to build a version of it from sources (github),
it requires libpcre and libltdl (libtool).

We already have a test that relates to cvsnt:
test-convert-cvsnt-mergepoints.t

cvsnt installs: cvs, cvslockd, cvsnt, cvsscript

I think we should definitely have a check for cvsnt because it makes
the version checks for cvs make a lot more sense.

When I use the version I built, cvs --version says:
