fix(ops/nixos): use builtins.storePath to avoid dumping pkgs.path r/4185

This is a less invasive way to achieve the same goal as cl/5681, by
preventing the already existing nixpkgs store path from being dumped
again at the call site. To support nixpkgsBisectPath, we simply check if
pkgs.path is below builtins.storeDir and use builtins.storePath based on
that.

This is actually similar to the approach taken in the nixpkgs
documentation system which tries to limit the amount of nixpkgs that
needs to be dumped by using filterSource on specific subtrees of
nixpkgs. For this to work it has to insist on pkgs.path being an
ordinary Nix path, though.
