Do not review removed permissions

Removed permissions don't participate in the permission model, hence we
should ignore them everywhere.

The problem was that if we set them as "review-required" other code gets
confused as an app that has been reviewed still has some permissions with
this flag set.

Test: 1. Installed legacy app that needs storage access (verified
         permission flags)
      2. reviewed permisisons (verified permission flags)
      3. reset app (verified permission flags)
      atest android.appsecurity.cts.PermissionsHostTest#testCompatDefault22 (while in isolated storage mode)
      atest android.appsecurity.cts.PermissionsHostTest#testReviewPermissionWhenServiceIsBound (while in isolated storage mode)
