Dialer: Fix crash when trying to close system dialogs

* https://developer.android.com/about/versions/12/behavior-changes-all#close-system-dialogs
* I tried removing it but then calling back someone does so behind the
  notification drawer
* Since this is a system app we can still use it but have to allow the
  permission and whitelist it
