refactor(ci): use the same test framework for headless client and IPC…

… service (#4943)

This will fix an issue with `linux-group` and `token-path` that happens
when I try to split up the binaries.

```[tasklist]
### Before merging
- [x] Fix linux-group. That stub-ipc-client command doesn't even exist anymore
```
