[PATCH] lib/crypto: sha256: Add tests for HMAC-SHA224 and HMAC-SHA256

[Eric Biggers <ebiggers@kernel.org>]

Now that there's a library API for HMAC-SHA224 and HMAC-SHA256, update
sha224_kunit and sha256_kunit to test it.  This mirrors the tests for
HMAC-SHA384 and HMAC-SHA512 in sha384_kunit and sha512_kunit.  The test
vectors were generated using scripts/crypto/gen-hash-testvecs.py.
