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

Browse Source 
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
