Remove Camellia ciphersuites (2014)

Some background:

In 2014, Mozilla disabled support for all TLS ciphersuites using the block cipher Camellia [1] after this blog post [2]. That blog post that discussed on HN at the time [3].

In light of the latest round of TLS attacks (SWEET32) [4], 3DES -- an old block cipher occasionally kept in use for compatibility with very old systems -- will likely be deprecated for good. This will leave mainstream browsers with exactly one block cipher (AES), and exactly one stream cipher (ChaCha20).
