perf data: Fix building in 32 bit platform with libbabeltrace



On ARM32 building it report following error when we build with
libbabeltrace:

  util/data-convert-bt.c: In function 'add_bpf_output_values':
  util/data-convert-bt.c:440:3: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Werror=format]
  cc1: all warnings being treated as errors

Fix it by changing %lu to %zu.
