tools/gpio/gpio-event-mon: fix warning

PRIu64 is defined in user space to match libc's uint64_t definition.
However, gpioevent_data structure in the kernel is defined using the
kernel's own __u64 type.

gpio-event-mon.c: In function ‘monitor_device’:
gpio-event-mon.c:102:19: warning: format ‘%lu’ expects argument of type
    ‘long unsigned int’, but argument 3 has type ‘__u64 {aka long long
    unsigned int}’ [-Wformat=]
   fprintf(stdout, "GPIO EVENT %" PRIu64 ": ", event.timestamp);
                   ^~~~~~~~~~~~~~
  LD       /tmp/kselftest/gpiogpio-event-mon-in.o
  LINK     /tmp/kselftest/gpiogpio-event-mon

Fix is to replace PRIu64 with llu, which we know is what the kernel uses
for __u64.
