Conditional build dependencies seem to be resolved on wrong Fedora version

[hroncok]

See pytest on f32. It says:

No package found for: (python3-importlib-metadata if python3 < 3.8)

While python3 on Fedora 32 is 3.8.

I can probably workaround this by adding an %if around the BR and rebuild the package, but I wonder how does the dependency resolution actually work. Is it resolved on some other Fedora version?

I can reproduce this issue locally. Reproducer: https://gist.github.com/mizdebsk/2ff126556cff0fa42d8111e2094c2033

Koschei resolves dependencies using libdnf. It seems that libdnf is checking python3 version on the system it is running, not in configured sack. This will require further investigation.
