nixos/activation-script: ensure gcroots dir exists
If the Nix daemon has never been enabled (nix.enable has always been set to false), the gcroots directory won't exist. If the Nix daemon is later enabled, the GC roots for booted-system and current-system will be missing, and they might end up being garbage collected. Since it's cheap to add GC roots even if the daemon will never be enabled, let's just always add them so we're okay in the case where the daemon is enabled later.
