fix(nix/buildkite): read & print the store path of built derivations

Browse source 
This was useful to have in CI, e.g. when targeting a specific NixOS
system. The actual result symlink which is printed is not useful.

Alternative solution would be to change the wrapping of this so that
we conditionally create the symlink for extra steps, but I think it's
not worth the complexity of evaluating the step twice.
