Simplify CI_GROUP command to avoid having massive results + use package scripts from python3

This avoids having CI_GROUP as PACKAGE to avoid having as result everything it PEERDIRS and contains. Its PEERDIRs still be built and cached, but won't become single massive result. Though if UNION or PACKAGE is PEERDIRed they will be preserved in autocheck grah and will be cached as denedency, but not as result.
