Ravi Bangoria 3c723f4497 perf test: Fix lock contention test 
Couple of independent fixes:

1. Wire in SIGSEGV handler that terminates the test with a failure code.

2. Use "--lock-cgroup" instead of "-g"; "-g" was proposed but never
   merged. See commit 4d1792d0a2 ("perf lock contention: Add
   --lock-cgroup option")

3. Call cleanup() on every normal exit so trap_cleanup() doesn't mistake
   it for an unexpected signal and emit a false-negative "Unexpected
   signal in main" message.

Before patch:

  # ./perf test -vv "lock contention"
   85: kernel lock contention analysis test:
  --- start ---
  test child forked, pid 610711
  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 --lock-cgroup
  Unexpected signal in test_aggr_cgroup
  ---- end(0) ----
   85: kernel lock contention analysis test                            : Ok

After patch:

  # ./perf test -vv "lock contention"
   85: kernel lock contention analysis test:
  --- start ---
  test child forked, pid 602637
  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 --lock-cgroup
  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)
  [Skip] Could not find 'unix_stream'
  Testing perf lock contention --callstack-filter with task aggregation
  [Skip] Could not find 'unix_stream'
  Testing perf lock contention --cgroup-filter
  Testing perf lock contention CSV output
  ---- end(0) ----
   85: kernel lock contention analysis test                            : Ok
