Jiri Olsa ef8a257b4e bpftool: Fix generated code in codegen_asserts
Arnaldo reported perf compilation fail with:

  $ make -k BUILD_BPF_SKEL=1 CORESIGHT=1 PYTHON=python3
  ...
  In file included from util/bpf_counter.c:28:
  /tmp/build/perf//util/bpf_skel/bperf_leader.skel.h: In function ‘bperf_leader_bpf__assert’:
  /tmp/build/perf//util/bpf_skel/bperf_leader.skel.h:351:51: error: unused parameter ‘s’ [-Werror=unused-parameter]
    351 | bperf_leader_bpf__assert(struct bperf_leader_bpf *s)
        |                          ~~~~~~~~~~~~~~~~~~~~~~~~~^
  cc1: all warnings being treated as errors

If there's nothing to generate in the new assert function,
we will get unused 's' warn/error, adding 'unused' attribute to it.
