tick-broadcast: Fix the printing of broadcast masks
Today the number of bits of the broadcast masks that is output into /proc/timer_list is sizeof(unsigned long). This means that on machines with a larger number of CPUs, the bitmasks of CPUs beyond this range do not appear.
Fix this by using bitmap printing through "%*pb" instead, so as to output the broadcast masks for the range of nr_cpu_ids into /proc/timer_list.
