[stow] Don’t fold directories when stowing files

Folding means that if stow discovers a parent directory for a project or a file
in it exists, it doesn’t create the directory structure and then links the file,
instead it makes a symbolic link between the directory.

This means that any files created in that directory show up in this repository.

The upside of that situation is that if I remove or rename files, and the
directory it’s in is folded, it doesn’t leave dead links around.
