Revert changes to make build targets transitive

This is no longer needed now that we update NuGetizer package reference to always be PrivateAssets=all, to account for users not doing it (misconfig issue).

This also fixes the issue with multi-targeting projects referencing nugetizer now since we had the wrong path for importing targets in that case.
