Peter Hoeg 897834f015 nixos/nix-optimise: be smarter about when we run the store optimiser
We might be inside a NixOS container on a non-NixOS host, so instead of not
running at all inside a container, check if the nix-daemon socket is writable as
it will tell us if the store is managed from here or outside.

Fixes #63578
