Parse broadcast arp responses via arping (iputils) properly
ARP replies may/do contain two MAC addresses when using iputils's
arping so we have to use the first one because it's always the "From"
address - which is what we want.
Thanks to Stefan Knoblich <s.knoblich@axsentis.de> for the fixed pattern.
