Follow up on this: I am able to evaluate this `service` expression in
`guix repl`. I am also able to use `,lower` and `,build` on the
`plain-file` in the REPL. Building the system with an empty list for the
actions works.

Maybe this is a bug? It seems like this is the correct way to configure
polkit actions from what I can find.
