crostestutils: Fix gce_au_worker and its unittest
Make GCEAUWorker.VerifyImage respect the passed in "test" argument, as
is the case for all other AUWorkers.
Also, remove the unused "flexibility" feature that allowed customized
instance properties being defined from a board overlay specific json
file. That doesn't scale - the same board may have multiple builder
configs that want to run different test suites.
Updated the unit test as well.
