Subject: [PATCH] don't auto revoke Network and Sensors

These shouldn't be automatically removed since apps are currently
granted these by default for compatibility. Users have to explicitly
remove them rather than granting them. Apps would need to be aware of
them and request them from the user to treat them like the standard
permissions.
