Move listening to brightness changes to onStart/onStop.

Browse Source 
Currently, we register the brightness listener in onResume() and stop
listening in onPause(). When we launch the brightness selection bar, the
display settings is paused, and hence we don't get the brightness
update, and only refresh the percentage when the brightness bar is
dismissed.

Moving the listening logic to onStart()/onStop() instead, so that we
will get the updates all the time when the display settings is launched.
