[ruby/openssl] hmac: use EVP_PKEY_new_raw_private_key() if available
Current OpenSSL 3.0.x release has a regression with zero-length MAC
keys. While this issue should be fixed in a future release of OpenSSL,
we can use EVP_PKEY_new_raw_private_key() in place of the problematic
EVP_PKEY_new_mac_key() to avoid the issue. OpenSSL 3.0's man page
recommends using it regardless:
> EVP_PKEY_new_mac_key() works in the same way as
> EVP_PKEY_new_raw_private_key(). New applications should use
> EVP_PKEY_new_raw_private_key() instead.
