MINOR: lua: export applet and task handlers

The current functions are seen outside from the debugging code and are
convenient to export so that we can improve the thread dump output :

  void hlua_applet_tcp_fct(struct appctx *ctx);
  void hlua_applet_http_fct(struct appctx *ctx);
  struct task *hlua_process_task(struct task *task, void *context, unsigned short state);

Of course they are only available when USE_LUA is defined.

(cherry picked from commit 60409db0b1743d670e54244425f6e08c389b7dde)
[wt: backported to improve troubleshooting when the watchdog fires;
     while in 2.0 we also have hlua_applet_htx_fct(), it's not
     visible outside hlua_applet_http_fct() so we don't care]
