[PATCH 03/12] hw/ppc/spapr: Replace sprintf() by g_strdup_printf()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

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:

  hw/ppc/spapr.c:385:5: 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(mem_name, "memory@%" HWADDR_PRIx, start);
      ^
  1 warning generated.
