Title: Improve python tests for brew bots

Setting the PYTHONPATH because the bot.brew.sh has
system python per default and we tell our users
to set the PYTHONPATH.

In this go, also update to newer `build.with? 'python'`
instead of `python do` because this checks for
the args during build.

Further `def test` --> `test do`
