nixos/moonraker: Fix permission issues on tmpfiles

The configuration of tmpfiles was not creating the expected filesystem tree.
The cause was the missing path listing of `{moonraker}/tools` result in `{moonraker}/tools`
to be created with the owner set as `root:root` preventing `systemd-tmpfiles` from creating link for `klipper-estimator`
