cbuildbot_launch: Attempt PreLoad from /preload/chromeos.
Some builders will have a clean checkout preloaded at
'/preload/chromeos', so have the cbuildbot_launch script attempt to
preload the main checkout from that location.
This does nothing if the source checkout doesn't exist, or if the
current checkout is already populated.
