Subject: [PATCH] daemon: also ensureDefaultApparmorProfile in exec path
When 567ef8e7858c ("daemon: switch to 'ensure' workflow for AppArmor
profiles") was merged, it didn't correctly handle the exec path if
AppArmor profiles were deleted. Fix this by duplicating the
ensureDefaultApparmorProfile code in the exec code.
