Check the server did not use a TLS 1.2 cipher suite pre-TLS 1.2.

This check got refactored in OpenSSL 1.0.2 and broke in the process. Fix this
and add a test. Otherwise things like client auth can get slightly confused; it
will try to sign the MD5/SHA-1 hash, but the TLS 1.2 cipher suite may not use
SSL_HANDSHAKE_MAC_DEFAULT, so those digests won't be available.

Based on upstream's 226751ae4a1f3e00021c43399d7bb51a99c22c17.
