regression: 4002: add NIST hmac vectors
Adds NIST HMAC test vectors to regression case 4002 with CFG_HASH_NIST_VECTORS=y. Only the first test in each group is used if CFG_HASH_NIST_VECTORS_LIMITED=y. Without CFG_HASH_NIST_VECTORS=y, CFG_HASH_NIST_VECTORS_LIMITED has no effect. Signed-off-by: Olivier Masse <[email protected]>
