perf script: Add some missing event dumps

Browse Source 
When the -D option is used, the details of thread-map, cpu-map and
event-update events are not currently dumped. Add prints so that they are.

Example:

  # perf record --kcore sleep 0.1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.021 MB perf.data (7 samples) ]
  # perf script -D | grep 'THREAD\|CPU'
  0 0x4950 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 35116
  0 0x4978 [0x20]: PERF_RECORD_CPU_MAP: 0-7
  # perf script -D | grep -A4 'UPDATE'
  0 0x4920 [0x30]: PERF_RECORD_EVENT_UPDATE
  ... id:    147
  ... 0-7
