Remove references to `brew-cask` from `brew` man page.

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.

Show cask description in `brew cask info` command

Also add non-dummy URL in the test fixture, to match the name, version, etc.

Add missing `help` methods for external `cask` commands.

Use `CLI::Parser` for `cask` commands.

Allow iOS and iPhone at the beginning of descriptions.
