    bridge: Fix generation of dnsmasq's --dhcp-hostsfile option
    
    I added a host definition to a network definition:
    
    <network>
      <name>Lokal</name>
      <uuid>2074f379-b82c-423f-9ada-305d8088daaa</uuid>
      <bridge name='virbr1' stp='on' delay='0' />
      <ip address='192.168.180.1' netmask='255.255.255.0'>
        <dhcp>
          <range start='192.168.180.128' end='192.168.180.254' />
          <host mac='23:74:00:03:42:02' name='somevm' ip='192.168.180.10' />
        </dhcp>
      </ip>
    </network>
    
    But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get
    added to the dnsmasq command. The patch below fixes it for me.
