perf script: Add some missing event dumps
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
