Add an option that allows all mmap or mmap2 events to be rewritten as
mmap2 events with build IDs.

This is similar to the existing -b/--build-ids and --buildid-all options
except instead of adding a build_id event an existing mmap/mmap2 event
is used as a template and a new mmap2 event synthesized from it.

As mmap2 events are typical this avoids the insertion of build_id
events.

Add test coverage to the pipe test.
