MINOR: haload: move statistics header printing to mtask_cb

Move the header printing logic from hld_init to mtask_cb using a static flag.
This ensures the header is displayed only when the main task starts
processing, avoiding issues where the header might be printed before other
haproxy initialization messages or unexpected early exits.
