[ruby/openssl] ssl: call SSL_CTX_set_ecdh_auto() on OpenSSL 1.0.2 only
SSL_CTX_set_ecdh_auto() exists in OpenSSL 1.1.0 and LibreSSL 2.6.1, but it is made no-op and the automatic curve selection cannot be disabled. Wrap it with ifdef to make it clear that it is safe to remove it completely when we drop support for OpenSSL 1.0.2.
