    Fix the Keyfile Test on Windows
    
    Windows will not allow one to write to a temp file opened by g_mkstemp()
    by opening another fd associated with it before one closes the fd that
    is returned by g_mkstemp(), which will cause the test_save test to fail.
    
    Fix this by using a variable to store the fd from g_mkstemp() and checking
    it, and call close() on that variable before attempting to call
    g_key_file_save_to_file() on the temp file as that will attempt to open
    another fd (which would not work) associated with that temp file.
