Subject: [PATCH] nixos/home-assistant: make service reloadable

This allows quick reloads using the following trick:

$(nix-build --show-trace --no-out-link \
  -E '(with import <nixpkgs/nixos> {};
       pkgs.writeScript "update-hass-config"
       config.systemd.services.home-assistant.preStart)')
systemctl reload home-assistant
