util/broadcom/secimage: Add OpenSSL 1.1 support

The `secimage` utility uses OpenSSL to calculate HMAC, which it does in
a rather unorthodox way, using deprecated `HMAC_CTX_init` API and
repeated calling of `HMAC_Init_ex` without a clear reason. The former
causes build errors with OpenSSL 1.1 while the rest of the
`HmacSha256Hash` function is confusing and overly complex.

Make `HmacSha256Hash` use a single OpenSSL API call. Test passed:
resulting signed binary remains identical.
