worker: respect C-c on sudo nix-build

Browse source 
While debugging something else I observed that latest `main` ignores
`Control-C` on `sudo nix-build`.

After reading through the capnproto docs, it seems as if the promise
must be fulfilled to actually terminate the `promise.wait()` below.

This also applies to scenarios such as stopping the client
(`nix-build`), but the builders on the daemon-side are still running,
i.e. closes #540
