regression 4002: add CMAC test case with a 16 bytes increment

Add a CMAC subtest where do_update operations are done with a data
input size of 16 bytes.
This is a test case for a bug in the CAAM CMAC driver which would not
handle properly consecutive do_update operations with input data size
of 16 bytes.
