store ':any' pseudo-packages with 'any' as architecture

Previously we had python:any:amd64, python:any:i386, … in the cache and
the dependencies of an amd64 package would be on python:any:amd64, of an
i386 on python:any:i386 and so on. That seems like a relatively
pointless endeavor given that they will all be provided by the same
packages and therefore also a waste of space.
