    scripts: add missing regex for dl_cleanup script
    
    Regex xxx-YYYY-MM-DD-GIT_SHASUM was missing. Add the new regex to improve
    and better find outdated package. This also fix a bug where some bug were
    incorrectly detected as packagename-yyyy-mm-dd instead of packagename due
    to them be parsed by the wrong parser
    
    Example:
    
        openwrt-keyring-2021-02-20-49283916.tar.xz
