Fix PemKeyConfigTests (#55577)

We were creating PemKeyConfig objects using different private
keys but always using testnode.crt certificate that uses the
RSA public key. The PemKeyConfig was built but we would
then later fail to handle SSL connections during the TLS
handshake eitherway.
This became obvious in FIPS tests where the consistency
checks that FIPS 140 mandates kick in and failed early
becausethe private key was of different type than the
public key
