[recipes/list-new: 6/14] Add a debug env var

[Matthias Clasen <matthiasc src gnome org>]

commit 0a5f62c4406cfcdb933a72efdf9b64e597e8c219

    Add a debug env var
    
    Setting RECIPES_DATA_DIR when running unsandboxed will let me
    use recipes to edit that data in the my git checkout, which
    makes it much easier to edit contributed recipes.
