    extractor: Do not fail if parent folders don't exist
    
    Currently, it is not possible to extract archives that don't explicitly
    contain parent folders. This is unintentional regression caused by commit
    adb067e6. Let's simply ignore G_IO_ERROR_NOT_FOUND errors when looking
    for symlinks to fix this.
