aa-autodep: load abstractions on start
So far, aa-autodep "accidently" loaded the abstractions when parsing the existing profiles. Obviously, this only worked if there is at least one profile in the active or extra profile directory.
Without any existing profiles, aa-autodep crashed with KeyError: '/tmp/apparmor.d/abstractions/base'
Prevent this crash by explicitely loading the abstractions on start.

I propose this patch for 2.11.master
