Verify stage status from CIDB for results_lib.Result.

1.When timeout happens and background tasks are killed, the statuses
of the background stage tasks may get lost. BuildSucceededSoFar may
still return build_succeess = True when the killed stage tasks were
failed. So add one more verification step in _BuildSucceededFromCIDB
to check the stage status in CIDB.
2.Added error logs to see why the failed status cannot be recorded
correctly.
3.Record failure Result when WaitUntilReady returns False.
