charm: Drop resource from rutabaga charm

This was only ever for local development convenience, and it's usually much easier to just fetch the resource from Swift. Now that we're trying to upload the charm to Charmhub, having a resource attached to it is an active impediment, because Charmhub doesn't have a good way to deal with optional resources; so just drop it.
