Core/Crypto: Transitional Cryptography update for OpenSSL 1.1 (#21534)

Support for both OpenSSL 1.0 LTS and OpenSSL 1.1 versions.

Many Linux distributions are still on 1.0 and will stay on LTS for quite
some time.

Port of CMaNGOS commit: https://github.com/cmangos/mangos-wotlk/commit/e1b0048f052eda46bb27d20224d0339960816ac2
