Change isProcStateBackground() cutoff to PROCESS_STATE_BOUND_FOREGROUND_SERVICE

isProcStateBackground() mostly is used to determinte when to call registered IUidObserver's
onUidActive() and onUidIdle() callbacks. CameraServer and AudioServer
are the two most notable IUidObserver.

Since AppOps uses PROCESS_STATE_BOUND_FOREGROUND_SERVICE as foreground state cutoff. It is
better we consolidate other part of code use the same proc state as
foreground cutoff.
