Please unblock package fwknop

[ Reason ]
The AppArmor profile was incorrectly installed in the systemd
system service path:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1034055

[ Impact ]
I'm not sure whether it would cause any actual problems, but it is likely a
policy violation and the bug reporter did file it as an RC bug.

[ Tests ]
I upgraded to the version I uploaded to unstable yesterday and confirmed
that the file is in the new location:

  $ dpkg -L fwknop-apparmor-profile | grep usr.sbin.fwknopd
  /usr/share/apparmor/extra-profiles/usr.sbin.fwknopd

[ Risks ]
Trivial fix. I made it so that the AppArmor profile is not automatically
enabled either to avoid changing (i.e. fixing) the behavior compared to what
it was in -15.

So this should be a no-op in terms of functionality.

[ Checklist ]
  [x] all changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in testing
