Commit 82c1f13de315 ("selftests/bpf: Add more stats into veristat")
introduced new stats, added by default in the CSV output, that were not
added to parse_stat_value, used in parse_stats_csv which is used in
comparison mode. Thus it broke comparison mode altogether making it fail
with "Unrecognized stat #7" and EINVAL.
One quirk is that PROG_TYPE and ATTACH_TYPE have been transformed to
strings using libbpf_bpf_prog_type_str and libbpf_bpf_attach_type_str
respectively. Since we might not want to compare those string values, we
just skip the parsing in this patch. We might want to translate it back
to the enum value or compare the string value directly.

Looks good, thanks!
