pkgset: Add object representing a package set on disk

Once a package set repo is written to disk, let's use this object that
connects the repository path with the mapping of packages.

This change also makes it explicit where the dependency on package set
repos are. In the original codebase, any part of code could generate a
path to the repo, even if that repo has not yet been written.
