daemon: Enable health check for ipvlan datapath

Currently, it runs in the veth mode which makes probes to remote
endpoints to fail because Docker sets the default policy of
the FORWARD chain in the filter table of iptables to DROP, and
we don't install any rules (w/ `--install-iptables-rules=false`)
to allow forwarded traffic to a subnet managed by Cilium.
