feat(ingredients): switch to home module
I've written another nilla module for homes to use sugared ingredients.
Much like the system module, portable submodules aren't suitable because
of a general lack of portability TwT...
Unlike the system module, homes can't currently have their modules
array removed as we seem to be using it to set the home directory and
state version (arguably these should be in a user module and common
respectively - or we could put them both in common and generate the
directory from the name of the home)
