Remove build/egg directories from worker vendor trec-car-tools
After updating the worker service to use Python 3.9.18, I got this update in its `trec-car-tools` vendor (file `services/worker/vendors/trec-car-tools/python3/trec_car_tools.egg-info/PKG-INFO`):
```
Requires-Dist: cbor>=1.0.0
Requires-Dist: numpy>=1.11.2
```

This PR removes unnecessary vendor `build` and `.egg-info` directories (which are automatically recreated at install).
