commit 2fe7c2f99440d52613e1cf845c96e8e463c28111 upstream.

Some platforms, such as mips64, don't map __u64 to long long unsigned
int so using %llu produces a warning:

gpio-event-mon.c:110:37: warning: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘__u64’ {aka ‘long unsigned int’} [-Wformat=]
  110 |   fprintf(stdout, "GPIO EVENT at %llu on line %d (%d|%d) ",
      |                                  ~~~^
      |                                     |
      |                                     long long unsigned int
      |                                  %lu
  111 |    event.timestamp_ns, event.offset, event.line_seqno,
      |    ~~~~~~~~~~~~~~~~~~
      |         |
      |         __u64 {aka long unsigned int}

Replace the %llu with PRIu64 and cast the argument to uint64_t.
