Correct KeySetId value when returned by AddKey

Browse Source 
[ Merge of http://go/wvgerrit/25643 ]

The MediaDrm#provideKeyResponse API states that an empty byte array is
returned when the license type is streaming or release but a non-empty
value was being returned in some cases.

The KeySetId is now returned when the license type is offline or when
the license is streaming and has a secure stop associated with it.

Test: Verified by request_license_test integration tests. Tests have been
      modified to validate the returned Key Set Id values.
