Fixes a hypothetical security issue related to privilege escalation via rootwrap/privsep. A potential vulnerable service could previously allow writes to its rootwrap/privsep config and thus allow for more commands to be run with root privileges via rootwrap/privsep. For a succesful attack, this would also require the service to allow to run arbitrary commands via rootwrap/privsep. Thus far, no such vulnerabilities have been reported and thus this fix is simply strengthening the container images against such an issue in the future.
