dnsmasq: fix dhcp-host entries with empty macs
Due to improper localization of helper variables, "config host" entries without a given mac address may inherit the mac address of a preceeding, leading to invalid generated netive configuration. Fix the issue by marking the "macs" and "tags" helper variables in dhcp_host_add() local, avoiding the need for explicitely resetting them with each invocation.
