[PATCH 1/2] also consider DIR:-type ccaches

[Nalin Dahyabhai <nalin-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

If we encounter a subdirectory while scanning a directory for a user's
ccache, check if it's a "DIR" ccache.  Otherwise, continue as before,
checking if it's a "FILE" ccache if it looks like a regular file.
