systemd AppArmorProfile= directive unavailable leads to not loading AppArmor profile on Debian jessie
Tor version: 0.2.7.6-1~d80.jessie+1 Tor version installed from: deb.torproject.org
/lib/systemd/system/tor@default.service uses AppArmorProfile=system_tor.
Debian jessie's (currently: Debian stable) version of systemd was compiled without AppArmor support.
(The systemd version that is available from Debian stretch (currently: Debian testing) has systemd >= 217 has AppArmor support.)

Therefore the AppArmor profile will not be load.
