Subject: [PATCH] cleanup: fix stale cask detection.

This method is also run to check formulae and if a formula and cask have
the same name (e.g. `cmake`) then this method would mark all formulae
downloads to being stale.

Instead, check the `dirname` (which we're using for globs anyway) to
double check that this is definitely a stale cask.
