[PATCH 01/12] ui/console-vc: Replace sprintf() by g_strdup_printf()

[Philippe Mathieu-Daudé]

sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1,
resulting in painful developper experience.

Replace sprintf() by g_strdup_printf() in order to avoid:

  [702/1310] Compiling C object libcommon.fa.p/ui_console-vc.c.o
  ui/console-vc.c:824:21: warning: 'sprintf' is deprecated:
    This function is provided for compatibility reasons only.
    Due to security concerns inherent in the design of sprintf(3),
    it is highly recommended that you use snprintf(3) instead.
    [-Wdeprecated-declarations]
                    sprintf(response, "\033[%d;%dR",
                    ^
  1 warning generated.
