rust-cpython: remove invalid __package__ attribute Since mercurial.rustext is a package, its __package__ should be, if set, "mercurial.rustext". AFAIK, we don't have to set this attribute manually as the rustext module will be imported by the system importer. https://stackoverflow.com/a/21233334/10435339
