To allow ddc sdk kernel generation internally, add a way to provide paths to dependent files explicitly, instead of assuming relative from Platform.script. Also remove .packages file parameter. We don't have this file internally and sdk shouldn't depend on any of packages anyway, so it just work without this option.
