tools: bpftool: introduce --json and --pretty options
These two options can be used to ask for a JSON output (--j or -json),
and to make this JSON human-readable (-p or --pretty).
A json_writer object is created when JSON is required, and will be used
in follow-up commits to produce JSON output.
Note that --pretty implies --json.
Update for the manual pages and interactive help messages comes in a
later patch of the series.
