overlayworkingctx: remove misleading trailing slash from directory pattern
The paths passed into the matcher are normalized (this applies to
include patterns and regular patterns, and to both glob kind and path
kind), so the regex for input "foo/" ended up being "foo(?:/|$)".
Once we have a (recursive) pattern kind only for directories, we could
switch to that here and remove the "mfiles[0] == path" check. Until
then, let's at least make it not misleading.

This directory is meant to cache artifacts useful for tests (such as bundle).
Those artifacts need to be cached because they are slow to regenerate on each
test but too large to be tracked within the repository. They are not expected
to change between each run and can be cached.
The `./scripts/` contains code to generate the artifact while the `cache`
directory contains resulting artifact.
