    extractor: Fix extraction of readonly folders
    
    If archive contains read-only folders, the extraction of their children
    fails with the "Permissions denied" error. This is because the folder
    permissions are restored immediately before writing their children.
    Let's do not restore unix mode before writing the children to fix
    this issue.
