Reset TPM and delete all state files before running OOBE update tests.
At the moment, OOBE AU autotests will run differently depending on how
long it has been since a DUT was provisioned. If the tests are run directly
after provisioning they will run as expected. If they are run after a
different autotest has logged into Chrome they will be run in a "nearly new"
state. This "nearly new" state is a result of chrome.Chrome(auto_login=False).
This resets some settings and makes the OOBE welcome screen appear. However,
update_engine will still believe we are already passed OOBE and won't behave
_exactly_ like it would for a new user.
This CL fixes that since we want to test the flow for users turning on a
device for the first time.
