tools/hooks/ use flake8-import-order plugin

But it's pep8 rule keeps application-imports in the same group as
relative-imports. Changing it is not a matter of configuration but defining
our own style, which is tedious as it would require a setuptools entrypoint
just for that, so we inject manually the style.
