setup: further improve the error path for version retrieval

This is a new take at the problem that 8d390a13474d tried to tackle. There was
two issues after that previous improvement:

- the 0.0+ version could survive a bit too long and reaching the installer
  version and staying there.
- multiple use case where still failing.

So the new code is better at:
- always succeeding when running `make local` so that we can
  bootstrap a local version
- no using that fallback outside of `make local` to avoid distribution of
  version with the buggy version number.

The setup.py is a gigantic pile of spaghetti code, to the point where
pastafarian pilgrim started knocking at its core.

However I refrained from cleaning that up since the more to a `setup.cfg` means
this code should be deleted soon™.
