Turn on ODK tests in CE CDM test and fix test helper

Merge from Widevine repo of http://go/wvgerrit/122223

This adds the ODK unit tests to the CE CDM tests so that they run as
part of the presubmit tests.

The test helper had some pointer problems converting a bool to a
uint32, so it has been updated to handle this correctly.

Some other tests failed comparing signed to unsigned, to these have
also been fixed.
