    testattributes: Fix test on Windows
    
    The %p format indentifier is handled differently at least on Windows
    due to the underlying system CRT implementation, so check for the
    resulting string to see whether we have the desired results by calling
    g_strplit() on it and check whether the parts of the string match what
    we expect.  For the %p part, we use strtol() to see whether we have the
    expected numerical value.
