clingo: fix i out of n

The old concretizer just drops py-setuptools. Add it unconditionally then.

Might get us back to the issue with Python 3.6 :) 🎉

Sigh. @alalazo suggestions? Either python 3.6 fails cause the old concretizer doesn't know how to deal with conflicts on setuptools, or it just entirely ignores the conditional depends on for 3.12.

Wondering if we can use a variant, and construct the specs in a way that depends on the interpreter version when bootstrapping.

Also, it seems GA is in the middle of a migration, so we're getting Python versions randomly on macOS. This one https://github.com/spack/spack/actions/runs/6745185158/job/18336769272?pr=40861 (from the PR) is Python 3.11

You can try concretization locally I guess

Bit frustrating that Spack can barely self-bootstrap :)

Yes, it's frustrating to support Python 3.6 and Python 3.12 together. But bootstrapping started failing on a single case over eleven tested, so "can barely self-bootstrap" seems a bit too much 😉
