Merge #158261

158261: roachtest: set ulimit for TPC-E workload runner r=herkolategan a=stevendanna

A recent version upgrade of docker changed the default of LimitNOFILE:

> containerd v2.1.5 now uses systemd's default LimitNOFILE for containers,
> changing the open file descriptor limit (ulimit -n) from 1048576 to 1024. This
> extends a change introduced in Docker Engine v25.0 for build containers to all
> containers.

Here, I explicitly set the `ulimit` when launcing the container.

According to the release note, an alternative here is to update our docker configuration on install:

```
{
  "default-ulimits": {
    "nofile": {
      "Name": "nofile",
      "Soft": 1048576,
      "Hard": 1048576
    }
  }
}
```

Fixes #158243

Release note: None
