When exit abnormally in process mode, customize SIGINT and SIGTERM signal
handler to kill the forked child processes.

Before:

  # perf bench sched messaging -l 1000000 -g 1 &
  [1] 8519
  # # Running 'sched/messaging' benchmark:

  # pgrep sched-messaging | wc -l
  41
  # kill -15 8519
  [1]+  Terminated              perf bench sched messaging -l 1000000 -g 1
  # pgrep sched-messaging | wc -l
  40

After:

  # perf bench sched messaging -l 1000000 -g 1 &
  [1] 8472
  # # Running 'sched/messaging' benchmark:

  # pgrep sched-messaging | wc -l
  41
  # kill -15 8472
  [1]+  Exit 1                  perf bench sched messaging -l 1000000 -g 1
