For a Package object query, we almost always did .select_related('arch',
'repo). Refactor this into the manager as a 'normal()' method so we can
avoid sprinkling the same logic everywhere.

Split it up as it is growing rather large, and add all the package files
views to the mix so Google or anyone can pick those up. They get a slightly
lower priority (if that even matters).
