Fix PR pkg/47363.

Import 3.2 version of cvsps as devel/cvsps3.

From README,
The 3.x versions have changed significantly.  In 2012, CVS use is declining
swiftly (GNU CVS hasn't been updated since 2004) and the original use case
for this tool - browsing change sets in a live CVS repository - is obsolete.
The 3.x versions are more focused on the --fast-export mode.
