s390x: Fix HMAC digest detection
    
    Use EVP_MD_is_a() instead of EVP_MD_get_type() to detect the digest
    type. EVP_MD_get_type() does not always return the expected NID, e.g.
    when running in the FIPS provider, EVP_MD_get_type() returns zero,
    causing to skip the HMAC acceleration path.
