arp: source address selection
https://gerrit.fd.io/r/c/vpp/+/30197 introduced SAS and inadvertently
broke ping in a variety of situations:
https://jira.fd.io/browse/VPP-1992
https://jira.fd.io/browse/VPP-1970
https://lists.fd.io/g/vpp-dev/topic/84038840
all of which seem to be rooted in situations where there's literally
nothing smarter ping can do for source address selection than
to pick the first IP on the interface. This can happen for:
1. P2P interfaces, see attempted fix: https://gerrit.fd.io/r/c/vpp/+/32801
2. Interfaces with /32 IP addresses intentionally assigned
After some discussion, this problem was partially fixed in
https://gerrit.fd.io/r/c/vpp/+/33449
Unforunately, while source selection was fixed in ping, it continued
to be broken in arp/nd. This gerrit builds on
https://gerrit.fd.io/r/c/vpp/+/33449
and fixes arp/nd.
