Update bootstrap.sh & setup.py

- pip install directly,
- only append once all code to fpylll-env/bin/activate so deactivating is not necessary
- pick up on return code of `make clean` in FPLLL, like G6K does.
- fix DeprecationWarning in setup.py and docs/conf.py for getting `__version__`
- depend on most recent cysignals (1.12.2) again as this one works again.

Closes: fplll#278
