Rename CVSNT "mergepoints" test and make it executable.

- rename test-convert-cvs-builtincvsps-cvsnt-mergepoints
  (and related files) to test-convert-cvsnt-mergepoints
- this ensures that the test will be run, but does NOT make
  it pass: in particularly, it fails regularly for me due
  to the inconsistent behaviour of CVS itself
- expect "Branchpoints:" in debugcvsps output
