cmd-koji-upload: Add support for node-image

 - cmd-koji-upload is tightly coupled to the Build
class and cosalib internals, which makes
supporting the new node-image layout challenging.

This commit introduces a way to maintain compatibility
with both the legacy and updated node-image styles for
brew uploads.

- This is a transitional fix — once the migration to
Konflux is complete, this compatibility layer will
no longer be necessary.
