requirements: add setuptools

cfriedt · cfriedt · commit 2069b7000ec0 · 2025-05-05T09:00:59.000-04:00
From a fresh installation of Ubuntu 24.04 with build-essential there
was an error when following the build instructions in the readme.

```
ModuleNotFoundError: No module named 'pkg_resources'
```

This was due to a missing `setuptools` package.

Add `setuptools` to `requirements.txt`.
