hack/make: ignore failure to stop apparmor

```
 ---> Making bundle: .integration-daemon-stop (in bundles/test-integration)
 ++++ cat bundles/test-integration/docker.pid
 +++ kill 13137
 +++ /etc/init.d/apparmor stop
 Leaving: AppArmorNo profiles have been unloaded.

 Unloading profiles will leave already running processes permanently
 unconfined, which can lead to unexpected situations.

 To set a process to complain mode, use the command line tool
 'aa-complain'. To really tear down all profiles, run 'aa-teardown'."

script returned exit code 255
