🐧 🍎 brew: Add Linuxbrew support

• Update brew task at Makefile. The task now invokes
  scripts/brew-select.zsh which includes the appropriate
  (home|linux)brew script
• FZF options added to the scripts/homebrew.zsh instead of living in
  the Make task
• Add scripts/linuxbrew.zsh
• Add linuxbrew/Brewfile

@todo: Organize the Brewfiles into the homebrew folder, separating
under common, macos and linux for better maintainability
