tests: Ignore fe80::ff:fe00:300 NS from AP for now in proxyarp tests

Browse source 
This NS seems to go out from the AP interface every now and then and it
makes proxyarp_open_ebtables_ipv6 fails inconveniently often. That frame
should not really be there, but it's not clear what exactly is needed to
stop it going through. It does not come from the test operations
themselves, so ignore it for now to keep test results cleaner.
