This treats it the same as TLS 1.0 and 1.1, which cause a warning to be shown
to users in Safari which they can click through if they want to visit a site
that hasn't transitioned to more modern TLS yet.  I also remove the use of
_TLSNegotiatedProtocolVersion which was only needed in OSes before
tls_protocol_version_t was available.
