Subject: perf inject: Lazy build-id mmap2 event insertion

Add -B option that lazily inserts mmap2 events thereby dropping all
mmap events without samples. This is similar to the behavior of -b
where only build_id events are inserted when a dso is accessed in a
sample.

File size savings can be significant in system-wide mode, consider:

  $ perf record -g -a -o perf.data sleep 1
  $ perf inject -B -i perf.data -o perf.new.data
  $ ls -al perf.data perf.new.data
           5147049 perf.data
           2248493 perf.new.data

Give test coverage of the new option in pipe test.
