PM / freezer: Reduce freeze timeout to 1 second for Android

Browse source 
Freezing processes on Android usually takes less than 100 ms, and if it
takes longer than that to the point where the 20 second freeze timeout is
reached, it's because the remaining processes to be frozen are deadlocked
waiting for something from a process which is already frozen. There's no
point in burning power trying to freeze for that long, so reduce the freeze
timeout to a very generous 1 second for Android and don't let anything mess
with it.
