app/crypto-perf: support AES-CCM

Browse Source 
According to the API, AES-CCM has special requirements
when setting IV and AAD fields.
The L2fwd-crypto app is updated to set the nonce (IV)
and AAD in the right positions in these two fields
(1 byte after start of IV field and 18 bytes after start
of AAD).
