Use new TLS method APIs with new LibreSSL

Browse source 
OpenBSD 5.8 includes LibreSSL 2.2.2, which finally brings the API up to
what they claim it is by implementing the new TLS client and server
method APIs. Therefore, in furtherance of commits a4c8c827 and 1a4e224a
we can build with the new APIs if building against (real) OpenSSL 1.1.0
or LibreSSL 2.2.2.
