selftests: mptcp: join: dump stats from history
In case of errors, dump the stats from history instead of using nstat.
There are multiple advantages to that:
- The same filters from pr_err_stats are used, e.g. the unused 'rate'
column is not displayed.
- The counters are closer to the ones from when the test stopped.
- While at it, the errors can be better presented: error colours, a
small indentation to distinguish the different parts, extra new lines.
Even if it should only happen in rare cases -- internal errors, or netns
issues -- if no history is available, 'nstat' is used like before, just
in case.
