…pythonGH-161706) Remove sys.path[0] in gzip, tarfile and zipfile command line interface to prevent shadowing standard library modules from extracted files. * Add sys._path0 variable. * pymain_sys_path_add_path0() sets sys._path0. * Add runpy._remove_sys_path0(). * gzip, tarfile and zipfile main functions now call _remove_sys_path0() to prevent shadowing stdlib modules from extracted files.
