Make S3 red-light flash adjustable.

This makes the timing for the S3 low-power indicator adjustable without
reflashing.

BUG=chrome-os-partner:8039
BRANCH=Link
TEST=manual

Boot, log in, run this to put the lightbar into demo mode:

  ectool lightbar demo 1
  ectool lightbar seq s3s0

The lightbar should act as though the system is asleep.

Then press the left arrow a couple of times and the down-arrow four or five
times.  You should see the red light pulse every 5 seconds or so.

Now run

  ectool lightbar params > /tmp/w

Edit /tmp/w to change the timing lines to this:

  100             # .s3_ramp_up
  100             # .s3_ramp_down

Then run

  ectool lightbar params /tmp/w

After a cycle or two, you should see the lightbar flash instead of pulse.
