perf scripting perl: Fix build error on Fedora 12

Cast __u64 to u64 to silence this warning on older distros, such as
Fedora 12:

    CC       /tmp/build/perf/util/scripting-engines/trace-event-perl.o
  cc1: warnings being treated as errors
  util/scripting-engines/trace-event-perl.c: In function âperl_process_tracepointâ:
  util/scripting-engines/trace-event-perl.c:285: error: format â%luâ expects type âlong unsigned intâ, but argument 2 has type â__u64â
  make[1]: *** [/tmp/build/perf/util/scripting-engines/trace-event-perl.o] Error 1
  make: *** [install] Error 2
  make: Leaving directory `/home/acme/git/linux/tools/perf'
  [acme@fedora12 linux]$
