This change adds options to the powerbtn console command to press and
release the power button.

BUG=chrome-os-partner:58123
BRANCH=none
TEST=manual
	'powerbtn press' force a power button press
	'powerbtn release' release the power button. This will not
	override the signal if the button is physically pressed.
