    xprops: Free latin1/utf8_string_from_results() return value with g_free()
    
    latin1_string_from_results and utf8_string_from_results use g_strndup,
    so the returned string should be freed with g_free, rather then with
    free or XFree. This fixes all free-s of buffers returned by these 2
    functions to properly use g_free.
