If an Android CTS module does not even start the amount of `FAILED`
tests in the invocation summary could still show up as 0, passing the
sanity check on the completion status, and `cts-tradefed` would not
reflect the module-level failure in the return value either.
So explicitly check that all included modules completed and, in case
they didn't, propagate this kind of failure to `EXIT_CODE`.
