Parse Checksum fields via pkgTagSection::Key, too

We abstract hashes a fair bit to be able to add new ones eventually,
which lead us to building the field names on the fly. We can do better
through by keeping a central place for these names, too, which even
helps in reducing code as we don't need the MD5 → Files dance anymore.
