[PATCH 14/26] perf tools: Add mmap3 events to --show-mmap-events option

[Jiri Olsa]

Displaying mmap3 events for --show-mmap-events option,
the build id is displayed within <> braces:

  $ perf script --show-mmap-events
  kill 12148 13893.519014: PERF_RECORD_MMAP3 12148/12148: 
<43938d0803c5e3130ea679cd569aaf44b98d9ae8> [0x560e7d7f..
  kill 12148 13893.519420: PERF_RECORD_MMAP3 12148/12148: 
<1805c738c8f3ec0f47b7ea09080c28f34d18a82b> [0x7f9e7dfc..
