/usr/local/openssl/cert.pem is the default location for security/openssl
so it should be handled just like /etc/ssl/cert.pem base OpenSSL. To
avoid having samples and copies with differing contents point both files
to the actual /usr/local/etc/ssl/cert.pem created by the sample. If users
have set their own content that is likely intended and should be enforced
across all three files.
