Fix HMAC compat layer function for SHA-1.

Browse Source 
This function would only accept the string "SHA" for SHA-1-based HMAC, but it
should also accept "SHA1." This is similar to how wolfSSL_EVP_get_digestbyname
allows both "SHA" and "SHA1." We didn't have a test for this in api.c. I added
one, and it failed before my fix here.
