systemd: disable mdns feature in resolved for zeroconf

DISTRO_FEATURE zeroconf installs avahi. If additionally resolved mdns

Mar 29 13:31:51 intel-corei7-64 avahi-daemon[752]: *** WARNING: Detected another IPv4 mDNS stack running on this host. This makes mDNS unreliable and is thus not recommended. ***
Mar 29 13:31:51 intel-corei7-64 avahi-daemon[752]: *** WARNING: Detected another IPv6 mDNS stack running on this host. This makes mDNS unreliable and is thus not recommended. ***
