    Fixes dnsmasq host file parsing with "addr6_list"

    This patch fixes:
    - The IPv6 tag added in the "host" file if is supported in
      dnsmasq. That shifts all other parameters in the register.
    - IPv6 registers can have more than one IP address; in this
      case, the method "_read_hosts_file_leases" should return a
      tuple per IP address.
