[PATCH 2/3] perf buildid-list: Requires ordered events

[Adrian Hunter <adrian.hunter@intel.com>]

perf buildid-list processes events to determine hits
(i.e. with-hits option).  That may not work if events
are not sorted in order. i.e. MMAP events must be
processed before the samples that depend on them so
that sample processing can 'hit' the DSO to which
the MMAP refers.
