L. E. Segovia ed6f2829b1 Cask: check support of quarantine's tools ...

- In some cases (usually old CLT versions) Swift is available but needs an
extra guard to use the quarantine API.
- xattr's native filesystem recursion is an Apple extension which is
not available in Mojave; so let's use xargs.
- Insert a quarantine support check in brew cask doctor.

Fixes Homebrew/homebrew-cask#51554, and fixes Homebrew/homebrew-cask#51538.
