apparmor: Additional runtime fixes

- We need various python3 modules and we can only really solve this
  problem by including all python3-modules.
- aa-easyprof needs to have its shebang corrected, do so.
- The apparmor initscript depends on functions that LSB does not require
  so we must provide them.  In some cases it's using non-standard
  function, so we just use more appropriate names.
- The apparmor sysvinit-style initscript assumes that
  systemd-detect-virt will exist on the filesystem.  Change this to
  check that it does before trying to execute it.

[for aa-easyprof:]
