options: treat outdated brews as installed
options: treat outdated brews as installed

`brew options --installed` will now "do the right thing".

There is getting to be a small but noticeable amount of code duplication
among commands that take options like "--installed" or "--all"; it may
be worth factoring this out into a method that will return a collection
of formula objects based on the options that are passed.
