perf test: Add more test cases for perf lock contention 

Check callstack filter with two different aggregation mode.

  $ sudo ./perf test -v contention
   88: kernel lock contention analysis test                            :
  --- start ---
  test child forked, pid 83416
  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
  Testing perf lock contention --type-filter (w/ spinlock)
  Testing perf lock contention --lock-filter (w/ tasklist_lock)
  Testing perf lock contention --callstack-filter (w/ unix_stream)
  Testing perf lock contention --callstack-filter with task aggregation
  test child finished with 0
  ---- end ----
  kernel lock contention analysis test: Ok
