Generated egg info potentially contains two empty files (except for a newline) that triggers an rpmlint warning. This doesn't appear to happen in Tumbleweed which makes including the lintrc to produce an error. Not including it produces a warning in older distros. We could account for that but I think it's not worth it just to silence an rpmlint warning so we might as well drop it.
Drop rpmlintrc disabling duplicate files check.
