tests: Fix proxyarp_open IPv4-from-bridge

Browse source 
There were couple of typos in the IP addresses and there was no coverage
for the normal unicast ARP response from the bridge (since non-wireless
device does not get proxied by the AP). In addition, it is better to
change the IP address used here to be unique to make the sniffer logs
easier to interpret.
