    Fudge glib fileutils test to pass on Windows
    
    1) Creating a directory with 0666 does not prevent
    traversal on Windows (ACL determines the possibility
    of traversal, and Windows mkdir() does not translate
    permission bits into ACL). Don't do the traversal check on Windows.
    
    2) Creating a file with 0555 also isn't translated into
    read-only ACL, Windows sets the read-only attribute instead,
    which blocks all changes, including changes to file times.
    Add the write permissions on Windows before changing file times.
