perf buildid-list: Introduce --with-hits option
Using this option 'perf buildid-list' will process all samples,
marking the DSOs that had some hits to list just them.
This in turn will be used by a new porcelain, 'perf archive',
that will be just a shell script to create a tarball from the
'perf buildid-list --with-hits' output and the files cached by
'perf record' in ~/.debug.
