jcstress: Test list should honor concurrency settings

```
jcstress-20240222. -c 1 -l | wc -l
4489
jcstress-20240222.jar -c 2 -l | wc -l
4489
jcstress-20240222.jar -c 4 -l | wc -l
4489
```

Then eg the runtime with `-c 1` may result in following message
```

But similar also happens with `-c 2` and `-c3 ` and sometimes with `-c 4`. Have not seen with bigger, but I have only 4 physical cores

If it is possible, the -l should honour the -c
