Upgrade Futuniuniu.app to v2.16.354, and linking with Chinese app name

Why are you using `:target`, here? `:target` should [only be used in select cases](https://github.com/caskroom/homebrew-cask/blob/master/doc/CASK_LANGUAGE_REFERENCE.md#target-should-only-be-used-in-select-cases), and this doesn’t really look like a good case. If the developer wanted to give the app bundle a different name, why not do it?

Instead, why not use [`tags :name`](https://github.com/caskroom/homebrew-cask/blob/master/doc/CASK_LANGUAGE_REFERENCE.md#tags-stanza-details)?
