Fix build with latest Nix

Browse source 
Recently a few internal APIs have changed[1]. The `outputPaths` function
has been removed and a lot of data structures are modeled with
`std::optional` which broke compilation.

This patch updates the code in `hydra-queue-runner` accordingly to make
sure that Hydra compiles again.
