add brewfile for setup in new osx environment

Brewfile can be run with `brew bundle` (detects current folder's `brewfile`) or
`brew bundle path/to/file`.

We do not run this in `setup.sh` yet, because the `brew bundle` halts execution
on any error, so this cannot be used just yet to keep a system up-to-date.
