Create a token for the AttributionSource ACameraManager passes to connectDevice

If an AttributionSource does not have a token, data delivery permission checks
fail with "Attempt to invoke interface method
'void android.os.IBinder.linkToDeath(android.os.IBinder$DeathRecipient, int)'
on a null object reference" due to the null binder. Create a token before
passing it to connectDevice.
