Subject: [PATCH 12/18] crypto/krb5: Implement the Camellia enctypes from
 rfc6803

Implement the camellia128-cts-cmac and camellia256-cts-cmac enctypes from
rfc6803.

Note that the test vectors in rfc6803 for encryption are incomplete,
lacking the key usage number needed to derive Ke and Ki, and there are
errata for this:
