Subject: don't send pkg from an unknown architecture via EDSP

APT's cache can include packages from architectures dpkg has no
knowledge about and can therefore not be installed for e.g. to allow
easy lookups. There is no point in telling external solvers about them
though and some of them might even be really talkative about ignoring
them if we do.
