Add a 1.0 second delay after all long power presses.

On Alex, after a long power button press, the EC seems to need a
short grace period before it recognizes a subsequent power button
press.  The delay is required whenever DUT software fails to shut
down within the 8 seconds, causing the EC to turn off power instead.

For simplicity, the change simply adds a delay after every long
power press.
