Prevent showing immersive confirmation unexpectedly

By design, if the user presses the power key twice within 5 seconds
(panic), it will show immersive confirmation again at the next time
entering immersive mode.

But there is a bug on calculating the time between pressing the power
key. The time get from event.getDownTime() will stop when the device
is sleeping without being charged.

So here uses SystemClock.elapsedRealtime() instead.
