build backend: use custom wrapper around flit

For pkgcore we need to run multiple preparations of generating files
before creating sdist or wheel. Flit is a very simple and nice build
backend, much more than setuptools.

Also migrate to use snakeoil.dist sphinx extension for generating man
and html, to remove various logic from `doc/conf.py`.
