package/matchbox-panel: add patch fixing GCC 14.x build issue

Fixes:

mb-applet-launcher.c: In function ‘get_launch_window’:
mb-applet-launcher.c:269:18: error: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
  269 |   time_t stime = time(NULL);
      |                  ^~~~

No autobuilder failures, it was hidden by other failures.
