The building of the perf tool failed in a SLES11 sp3 system with the
following compilation error:
cc1: warnings being treated as errors
util/scripting-engines/trace-event-perl.c: In function
‘perl_process_tracepoint’:
util/scripting-engines/trace-event-perl.c:285: error: format ‘%lu’
expects type ‘long unsigned int’, but argument 2 has type ‘__u64’
This patch replaces PRIu64 which is "lu" by the explicit "llu" to
fix this problem as __u64 is of type "long long unsigned".
