  1. bpf: don't answer ARP requests for endpoint IP 

    Previously, bpf_lxc was answering to all ARP requests. This causes
an issue in an scenario where a duplicate address check is being
conducted inside the container by sending an ARP request for the
endpoint IP for which no answer is expected. This fixes it by answering
to ARP requests for all IPs except the endpoint IP.

Fixes: cilium#10574
