Allow the ability for a system administrator to use `HOMEBREW_BREW_WRAPPER` and `HOMEBREW_FORCE_BREW_WRAPPER` variables to enforce the usage of a particular `brew` command for non-trivial (e.g. `brew --prefix` is considered trivial, it doesn't need to write to the prefix) Homebrew commands. This also introduces a `HOMEBREW_ORIGINAL_BREW_FILE` variable for some internal usage; `HOMEBREW_BREW_FILE` was being used internally for both "how should we shell out to Homebrew" and "what should we use to check permissions on Homebrew". `HOMEBREW_ORIGINAL_BREW_FILE` is now used just for the latter case. Inspired by conversation in https://github.com/Homebrew/homebrew-bundle/pull/1551 which suggested this was worth fixing in wider than just `brew bundle`.
