Remove util/openssl-update-copyright

It was useful at the time for a one-time run.  However, since it does
its work based on file modification time stamps, and those are
notoriously untrustable in a git checkout, it ends up being harmful.

There is a replacement in OpenSSL's tools repository, which relies on
git history.

Fixes #12462
