    scripts: signall: skip updating hash of previous kmods/
    
    Handle case where a sha256sums might contain previous kmods/. In such
    case packages.adb for previous kmods/ needs to be skipped as not
    included in the sign tar and already signed by previous runs.
    
    Skip is limited to kmods/ entry as those are the only entry expected to
    be present in the sha256sums but not included in sign tar.
