Badge the icon properly in policy transparency dialog

Following the pattern used within the Settings app to badge the icon.

For location setting, the dialog is shown in work profile user.
Thus ai.loadIcon badged the icon for the first time and
getUserBadgedIcon baged the second time.

Test: adb shell wm density 560 -> suspend an app -> launch the app ->
      observe the dialog. Repeat the test with original density.
