Subject: hmac: migrate from the low-level HMAC API to the EVP API

Use the EVP API instead of the low-level HMAC API. Use of the HMAC API
has been discouraged and is being marked as deprecated starting from
OpenSSL 3.0.0.

The two singleton methods OpenSSL::HMAC, HMAC.digest and HMAC.hexdigest
are now in lib/openssl/hmac.rb.
