flake.nix: Expose packages as legacyPackages

While the "packages" within Nix Flakes does make a few things a bit
simpler it also only allows us to export a flat structure.

However, in Vuizvui we want to use namespaces for the corresponding
package sets, since different packages could have different overrides
depending on the namespace of the corresponding author.
