Subject: [PATCH] perf tools: Fix a compiling error in probe-event.c for 32 bits machine

On 32 bits machine, there is a compile error:

    CC     util/probe-event.o
  util/probe-event.c: In function 'find_alternative_probe_point':
  util/probe-event.c:320:2: error: format '%lx' expects argument of type 'long unsigned int', but argument 5 has type 'u64' [-Werror=format]
  cc1: all warnings being treated as errors
  make[3]: *** [util/probe-event.o] Error 1

Fix it by using the PRIx64 for u64.
