Whitelist ManagedProvisioning from bg check

Notice that app put in this list is also exempted from doze.
Also, this only exempts us from the service restriction, but not the broadcast one.

Test: adb shell am make-uid-idle  --user 0 com.android.managedprovisioning
      && adb shell am broadcast -a android.intent.action.PRE_BOOT_COMPLETED -n com.android.managedprovisioning/com.android.managedprovisioning.ota.PreBootListener
      Observe there is no crash
