Subject: [PATCH] symm/t/sha...: Add official NIST HMAC test vectors.

I found some at last, annoyingly provided as PDF documents.
Unsurprisingly, the code passed first time.

Strange: the tests include two tests for the message `Sample message for
keylen=blocklen', exactly one of which has the key length equal to the
block length.  Whatevs.
