perf test: Update perf lock contention test

Add test cases for the task and addr aggregation modes.

  $ sudo ./perf test -v contention
   86: kernel lock contention analysis test                            :
  --- start ---
  test child forked, pid 680006
  Testing perf lock record and perf lock contention
  Testing perf lock contention --use-bpf
  Testing perf lock record and perf lock contention at the same time
  Testing perf lock contention --threads
  Testing perf lock contention --lock-addr
  test child finished with 0
  ---- end ----
  kernel lock contention analysis test: Ok
