perf test: Fix hists related entries

That got broken by d3a72fd8 ("perf report: Fix indentation of
dynamic entries in hierarchy"), by using the evlist in setup_sorting()
without checking if it is NULL, as done in some 'perf test' entries:

  $ find tools/ -name "*.c" | xargs grep 'setup_sorting(NULL);'
  tools/perf/tests/hists_output.c:      setup_sorting(NULL);
  tools/perf/tests/hists_output.c:      setup_sorting(NULL);
  tools/perf/tests/hists_output.c:      setup_sorting(NULL);
  tools/perf/tests/hists_output.c:      setup_sorting(NULL);
  tools/perf/tests/hists_output.c:      setup_sorting(NULL);
  tools/perf/tests/hists_cumulate.c:    setup_sorting(NULL);
  tools/perf/tests/hists_cumulate.c:    setup_sorting(NULL);
  tools/perf/tests/hists_cumulate.c:    setup_sorting(NULL);
  tools/perf/tests/hists_cumulate.c:    setup_sorting(NULL);
  $

Fix it.

After the patch the above failed tests complete successfully.
