Namhyung Kim 160d4af97b perf script: Add --show-cgroup-events option 
The --show-cgroup-events option is to print CGROUP events in the
output like others.

Committer testing:

  [root@seventh ~]# perf record --all-cgroups --namespaces /wb/cgtest
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.039 MB perf.data (487 samples) ]
  [root@seventh ~]# perf script --show-cgroup-events | grep PERF_RECORD_CGROUP -B2 -A2
