Fix build. (Shift3#17)

* Uses the new homebrew install method.
* Updates old installs by ensuring casks and homebrew are deep clones instead of shallow.
* Newer git requires a pull strategy defined in gitconfig
* Fedora has podman as a complete replacement for docker, so docker install not necessary.
