Correctly report TLSv1.2 only ciphers as negotiable with TLSv1.2

Browse Source 
Previously scan would report:
prio  ciphersuite                  protocols                    pfs_keysize
1     ECDHE-RSA-AES128-GCM-SHA256  SSLv3,TLSv1,TLSv1.1,TLSv1.2  ECDH,P-256,256bits
2     ECDHE-RSA-RC4-SHA            SSLv3,TLSv1,TLSv1.1,TLSv1.2  ECDH,P-256,256bits

Now it correctly reports:
prio  ciphersuite                  protocols                    pfs_keysize
1     ECDHE-RSA-AES128-GCM-SHA256  TLSv1.2                      ECDH,P-256,256bits
2     ECDHE-RSA-RC4-SHA            SSLv3,TLSv1,TLSv1.1,TLSv1.2  ECDH,P-256,256bits
