Describe your issue

The new topological search doesn't break the pip <-> python cycle properly, and thus installs pip before python. This breaks on Windows, as the Scripts folder does not exist before installing python, and then the entrypoint creation fails.

On Unix it will also fail to compile the .py files to .pyc (python is invoked for that).

How does libsolv knows how to break this cycle?

Not related to #2546 but leaving open since cycles are not taken into the implementation of topological sort.
