Íñigo Huguet 7fb4724efa core: dns: show in D-Bus if [global-dns] is defined but empty 
Clients like nmstate needs to know if the [global-dns] section is
defined or not, so they know if DNS configs from connections are
relevant or not. Expose it in D-Bus by always exposing "searches"
and "options" if it's defined, maybe as empty lists.
