Change default to build ChromeOS with AFDO.
Change the default USE flags to use AFDO since that is how the
released images are built. To build WITHOUT AFDO do:
build_chromeos.py --env='USE=-afdo_use' --board ....
BUG=None
TEST=Tested building with and without AFDO. Verified right USE
flags are generated.
