Get python targets building

I added 'black' to Biz/Lint.hs, but not the others because they rely on
dependencies being in the PYTHONPATH to work, so they are only relevant
in nix builds and repls.

I also made some other tweaks to the python checkPhase and linted all
the files. Everything should be building and linting correctly now.
