Revert OpenSSL commit aa6bb135

This reinstates the original license on this file. Don't bother bumping
the copyright year. Nothing interesting has happened in here since the
initial commit.

(There was one interesting commit though: "Don't care openssl_zmalloc()",
which is interesting due to the lack of care, not because it's copyright
worthy)
