Fix bpf_cookie failures due to missing bpf_testmod and flaky perf_event
triggering.

Tested:
  ./test_progs -t bpf_cookie/perf_event -vv (30 runs): 0 failures
  ./test_progs -t bpf_cookie -vv

  selftests/bpf: bpf_cookie: skip kprobe_multi tests without bpf_testmod
  selftests/bpf: bpf_cookie: make perf_event subtest trigger reliably
