Merged requested to merge cboltz/apparmor:cboltz-samba-bgqd into master
... and some rules in the smbd profile to execute it and send it a term signal.
samba-bgqd is (quoting its manpage) "an internal helper program performing asynchronous printing-related jobs."
samba-bgqd was added in Samba 4.15.
I propose this patch for 3.0 and master.
