Subject: [PATCH] Do not try to copy crl-tmp contents if empty.

The Kubernetes CronJob for syncing CRLs syncs them to a temporary folder
and then copies them to the real location once the sync is complete. If
the temporary folder is empty, the `cp` command throws an error. This
updates the bash script that manages the sync so that it will skip the
copy command if the temporary location is empty.
