cms: disallow AEAD ciphers and AES XTS
The CMS code doesn't support RFC 5083/5084 authenticated enveloped data
and outputs garbage that even itself can't decrypt for a reason that I
have not tried to pinpoint. So refuse using AEAD ciphers and AES XTS for
enveloped data from the cms "app" and throw an error pointing out that
this isn't supported.
OpenSSL have since added incorrect support for AuthEnvelopedData (ASN.1
and code review are hard), so doing this right will need both correct and
interoperable code, which I doubt anyone will bother to write anytime soon.
