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™.
