Allow short-service to hold a wake lock during doze

- Change the logic to "procstate <= BFGS, _or_ the UID has a short
service".

- We should clean up the logic once we figure out a better way to do it

- Also move the part of the logic to ActivityManager so we can udpate
the logic anytime without touching PowerManagerService.
