Extract-certs-pem writes pem files to a dedicated file; since it does not really work in cluster-environments it was never super helpful. This commit deprecates this file and, instead, adds log-certs-base64.zeek, which adds the base64-encoded certificate (which is basically equivalent with a PEM) to the log-file. Since, nowadays, the log-files are deduplicates this should not add a huge overhead.
