brew cleanup: don't remove higher version kegs.

Browse Source 
* Use version compare to only remove kegs with lower version than the
  current one, not higher version which might be from someone's
  branch.
* Do the same for cache cleanup.
  - Be conservative so that if a name detected from cache file is not
    the same as its formula then don't clean it.

Closes Homebrew/homebrew#15914.
