lbmap: Do not arping each service backend IP addr

Previously, we used to arping each service backend IP address to retrieve
the mac address of the next hop to the IP addr. The IP => mac mappings were
inserted into the Linux ARP table, so that NodePort's fib_lookup() could
find the relevant mapping.

However, it's enough to know "IP addr of next hop to backend IP addr" =>
"mac addr of next hop to node running backend" for fib_lookup() to succeed.
As the next hop IP addr is of a Cilium node, the mapping can be learned
by arping'ing the Cilium node once it has joined the cluster (same as
in the crypto case).
