Publisher: Clean up disk space before building

Some images (like slc9-gpu-builder) are too big for the free runner, so
we need to remove some stuff before, mostly unused language packages

Reference for the free disk space:
actions/runner-images#2840

Builder error message:
```
==> docker:    At least 11799MB more space needed on the / filesystem.
```
