Implement a budgie backgrounds sub-package and start symlinking dark variant

This PR implements a budgie backgrounds sub-package to be used as part of the default branding for Fedora Budgie Spin and Fedora Onyx, in a manner that can be made immutable across Fedora releases.

We are also now symlinking the "night" variant to "default-dark", as prior to this packages / contributors managing branding did not have an immutable path across releases for this image.
