Roman Reiss 77f35861d0 tls: more secure defaults
This updates the default cipher suite to an more secure list, which
prefers strong ciphers with Forward Secrecy. Additionally, it enables
`honorCipherOrder` by default.

Noteable effect of this change is that the insecure RC4 ciphers are
disabled and that Chrome negotiates a more secure ECDHE cipher.
