parser: Preserve unknown profiles when restarting apparmor init/job/unit

CVE-2017-6507

https://launchpad.net/bugs/1668892

The common AppArmor 'restart' code used by some init scripts, upstart
jobs, and/or systemd units contained functionality that is no longer
appropriate to retain. Any profiles not found /etc/apparmor.d/ were
assumed to be obsolete and were unloaded. That behavior became
problematic now that there's a growing number of projects that maintain
their own internal set of AppArmor profiles outside of /etc/apparmor.d/.
It resulted in the AppArmor 'restart' code leaving some important
processes running unconfined. A couple examples are profiles managed by
LXD and Docker.
