nixos/prometheus: make scrapeConfigs.*.static_configs.*.labels optional

Browse Source 
...by providing a default value of "no labels" (an empty attrset).

  $ nixos-rebuild test -I nixpkgs=.
  building Nix...
  building the system configuration...
  error: The option `services.prometheus.scrapeConfigs.[definition 1-entry 1].static_configs.[definition 1-entry 1].labels' is used but not defined.

which is unneeded, because labels _are_ optional.
