Enforce package visibility to the callbacks of the sync status
App can read installed sync content providers without requiring
any permission via the api ContentResolver#requestSync and
ContentResolver#addStatusChangeListener.
This cl enforces package visibility filter to the api
ContentResolver#addStatusChangeListener. Application without the
package visibility tag of the target applications in its manifest
cannot receive sync status callbacks of the target applications.
