TLS 1.1 and TLS 1.2 Support - use SSLv23_method() not TLSv1_method()

[Nick Lowe]

Great!

I had thought SSL_OP_NO_SSLv2 and SSL_OP_NO_SSLv3 were already being
set elsewhere when I grepped through the source.

For info, Radiator are also making a similar change for 4.14 to
support TLS 1.1 and TLS 1.2 from the server side:
