test: update parallel/test-crypto-keygen for OpenSSL 3
OpenSSL 3 returns a different error code.
We've just enabled testing against a dynamically linked OpenSSL 3 (https://github.com/nodejs/build/issues/2584) -- we did have a clean run on a copy of the job last week but that was before the test was recently changed in https://github.com/nodejs/node/pull/37076.
