Upgrade littlecheck to print all error lines

Browse source 
In #7459, asan printed error output. However, because we had a failure
on stdout already, littlecheck would only print the first unmatched
line from stderr, leading to output like

```
additional output on stderr:1:

    =================================================================
```

Which is of course entirely useless.

So in that case we just let it print *all* unmatched stderr lines, so
you'd get the full asan output, which presumably is of more use.

This upgrades littlecheck to 5f7deafcea4e58dd3d369eae069a3781bb6ce75e.
