perf lock contention: Fix a build error on 32-bit

Browse Source 
Fix a build error on 32-bit system:

  util/bpf_lock_contention.c: In function 'lock_contention_get_name':
  util/bpf_lock_contention.c:253:50: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'u64 {aka long long unsigned int}' [-Werror=format=]
     snprintf(name_buf, sizeof(name_buf), "cgroup:%lu", cgrp_id);
                                                  ~~^
                                                  %llu
  cc1: all warnings being treated as errors
