openssl: avoid deprecated version-specific ssl methods if necessary

* ext/openssl/extconf.rb: Check for SSL_CTX_set_min_proto_version()
  macro added in OpenSSL 1.1.0. Version-specific methods, such as
  TLSv1_method(), are deprecated in OpenSSL 1.1.0. We need to use
  version-flexible methods (TLS_*method() or SSLv23_*method()) and
  disable other protocol versions as necessary.
  [ruby-core:75225] [Feature #12324]

* ext/openssl/ossl_ssl.c: Use SSL_CTX_set_{min,max}_proto_version() to
  fix the protocol version.
