localrepo: move store() from store module

I want logic related to requirements handling to be in the localrepo
module so it is all in one place.

I would have loved to inline this logic. Unfortunately, statichttprepo
also calls it. I didn't want to inline it twice. We could potentially
refactor statichttppeer. But meh.
