First "ectool lightbar" command.

BUG=chrome-os-partner:8728
TEST=manual

I don't have a system that has both an EC and a lightsaber, so I can't be
certain this works, but I *think* it will.

I do have a Link proto 0.5. With that, you can say

  ectool lightbar test

and the EC console says it's poking at the lightbar, but of course there's
nothing there. If there was, it *should* flash in pretty colors. I have a
lightsaber attached to a BDS, and from the EC console running "lightsaber
test" does make it blink.
