Android 8 / 9 Location Permission Notice

* NOTE: Android 8.0+ unfortunately required us to add the "approximate location" permission as it's now required for apps that support Wi-Fi direct (because Wi-Fi direct leaks this information). FX does not ever actually query your location and this permission will only ever be asked for on Android 8.0 and later when using FX Connect. This requirement previously applied only to Android 9.0 but because FX now specifies full support for the latest Android API Android 8.0 also requires this permission.
