selftests/bpf: make veristat emit all stats in CSV mode by default

Make veristat distinguish between table and CSV output formats and use
different default set of stats (columns) that are emitted. While for
human-readable table output it doesn't make sense to output all known
stats, it is very useful for CSV mode to record all possible data, so
that it can later be queried and filtered in replay or comparison mode.
