bpf: egressgw: don't redirect to tunnel dev if EP is running on gateway node

When a client endpoint selected by an egress gateway policy is running
on the egress gateway node itself, there's no need to redirect the
endpoint traffic supposed to be forwarded to the gateway to the tunnel
device: we can just let it go through bpf_lxc, as it will eventually
reach the bpf_host program responsible for SNAT'ing it with the egress
IP.
