feat(scripts): support build artifact without compression

The github action `upload-artifact` always creates a zip tarball when
collecting it and this caused double-zip a zip in our case.
See the following issue for details:
   actions/upload-artifact#39

This change adds a cli parameter to build artifact without zip
compression. And let the action to create a tarball for us.

Test: build
