Files: allow target to be the home directory, for recursively-linked directories

Browse source 
In order to create assorted symlinks directly in the home directory, it might be necessary to have a `home.file` directive which targets the home directory directly.
This is only allowed for recursively-linked directories, as even a simply-linked directory would cause the system to break (due to a readonly ~/.nix-profile, among others)
