feat(bluefin-cli): Persist State of Cellar

Persist the state of Homebrew's Cellar for ublue-os#768

If the Cellar does not exist. It will be created in the User's home directory. It is then volume mounted into the container making it accessible on any distrobox enter for the container.

This also uses the brew_pkgs as a brewfile and brew_script to install/reinstall packages. The brew_script will first try to relink everything in the Cellar. However, just because an item is relink, doesn't mean it will be able to run necessitating a reinstall. Fortunately, any specified reinstalls seem to be quick.
