Fix import logic to make all imported packages be children of the `NameScopeId::Package` scope. Previously, indirectly-imported packages would end up as children of their importing package's scope, which resulted in them not being treated as packages at all, and in particular not being fingerprinted as packages. Fixing that caused a failure in the fingerprinting logic as we started to encounter packages with no correspoding import scopes. Instead of looking for import scopes, use a simpler mechanism to map packages to their package names, and clean up. Unfortunately the latter change churns all the fingerprints again :( Hopefully this is the last time for a while.
