Moved OS-specific logic to functions: - `find_ruby`: returns (via echo) Ruby that can be used - `usable_ruby`: checks whether Ruby satisfies Homebrew Pre-create OS-specific error messages: - `upgrade_fail`: message that is printed when Homebrew fails to upgrade vendor Ruby - `install_fail`: message that is printed when Homebrew fails to install vendor Ruby Unconditionally set `TERMINFO_DIRS` when installing/upgrading vendor Ruby **but** export it on Linux only. Motivation: move OS-specific logic to functions so that it's easier to understand the main steps.
