closureInfo: handle empty path set explicitly
Arguably, this is a bug in Nix's structuredAttrs: without structuredAttrs, exportReferencesGraph with an empty path set would still result in information being provided. With structuredAttrs, no info is provided for an empty path set. Nevertheless, we need to be able to build even if Nix has the bug, so work around it by checking for an empty path set and handling it explicitly.
