[PATCH 19/26] perf tools: Add buildid-list support for mmap3

[Jiri Olsa]

Add buildid-list support for mmap3 so we can display
hit dso objects buildid with filename for mmap3 data:

  $ perf buildid-list
  1805c738c8f3ec0f47b7ea09080c28f34d18a82b /usr/lib64/ld-2.31.so
  d278249792061c6b74d1693ca59513be1def13f2 /usr/lib64/libc-2.31.so
