brontide: the encrypted packet length is no longer the associated data
This commit modifies the current implementation to more closely match
what’s currently specified within the spec.

The encrypted+MAC’d packet length is no longer included as the
associated data for the encryption/decryption of transport messages.
This isn’t required as if an active attacker swaps out the encrypted
length in the byte string, the decryption+MAC check will simply fail as
the nonce won’t be in proper sequence.
