rpc: TLSv1_2_method() is deprecated in OpenSSL-1.1

Fedora 26 has OpenSSL-1.1. Compile-time warnings indicate
that TLSv1_2_method() is now deprecated. As per the SSL man page:

  TLS_method(), TLS_server_method(), TLS_client_method()
    These are the general-purpose version-flexible SSL/TLS methods.
    The actual protocol version used will be negotiated to the highest
    version mutually supported by the client and the server. The
    supported protocols are SSLv3, TLSv1, TLSv1.1 and TLSv1.2.
    Applications should use these methods, and avoid the version-
    specific methods described below.
  ...
  TLSv1_2_method(), ...
  ...

Note that OpenSSL-1.1 is the version of OpenSSL; Fedora 25 and RHEL 7.3
and other distributions (still) have OpenSSL-1.0.

TLS versions are orthogonal to the OpenSSL version.  TLS_method() is the
new — in OpenSSL-1.1 — version flexible function intended to replace the
TLSv1_2_method() function in OpenSSL-1.0 and the older (?), insecure
TLSv23_method(). (OpenSSL-1.0 does not have TLS_method())
