lang/ocaml: regenerate checksum for configure patch

distinfo from cvs:     trusted to convey hashes
patches from same cvs: untrusted thus require hashes to verify
absurdness: Any intruder that can modify the patch in cvs can also modify
            the distinfo file.

Only externally hosted patches require hashes.  Hopefully some day
thousands of future commits to distinfo files everywhere can be avoided by
making the framework smarter.  </rant>
