[CRYPTO] aead: Allow algorithms with no givcrypt support

Some algorithms always require manual IV construction.  For instance,
the generic CCM algorithm requires the first byte of the IV to be manually
constructed.  Such algorithms are always used by other algorithms equipped
with their own IV generators and do not need IV generation per se.
