chromeos_config: Take lakitu out of brillo

Considering the direction that the Brillo project is going, Lakitu probably
doesn't fit in there any more. There are some recent Brillo related changes that
aren't applicable to Lakitu, e.g., chrome-os-partner:45210 that enabled HWTests
for all Brillo boards. Things like this will continue to happen so let's move
early before we find us in a difficult situation.

This change tries to keep the config delta as minimal as just to disable hwtests
for Lakitu, so the risk of breakage is very low.

BUG=chromium:550601
TEST=cbuildbot/runtest cbuildbot/chromeos_config_unittest and compare the
generated config_dump.json with unchanged one.
