Subject: [PATCH] crypto: fix builds with older OpenSSL 3.0

Ubuntu 22.04's default libssl-dev still lacks EVP_PKEY_PRIVATE_KEY
even when fully updated. Provide the OpenSSL 3.0.12 definition when
the headers do not define it so --shared-openssl builds work.

Fixes: https://github.com/nodejs/node/issues/66926
