Currently lock task modes started by the activity flag
android:lockTaskMode behave differently from those started using
startLockTask(). With those changes lock tasks initiated by non-priv
apps cannot finish without calling into stopLockTask. Revoking the
whitelisting on a locked task will also kill that task, independently
of the way the lock task mode was started.
