libtraceevent: Print function pointer address when TEP_EVENT_FL_PRINTRAW is specified

When the TEP_EVENT_FL_PRINTRAW flag is specified in print_event_info(),
print function pointer addresses and not just the function pointer itself.

That is, instead of having just:

    ip=trace_printk_irq_work

Print:

    ip=trace_printk_irq_work (0xffffffffc06d0028)
