Remove support for OpenSSL older than 1.1.0

Browse Source 
OpenSSL 1.0.2 has been EOL from the upstream OpenSSL project for
some time, and is no longer the default OpenSSL version with any
vendor which package PostgreSQL. By retiring support for OpenSSL
1.0.2 we can remove a lot of no longer required complexity for
managing state within libcrypto which is now handled by OpenSSL.
