rc.d/static_arp for v6: static_ndp

[Frank Bartels]

Hi,

I've just noticed we have rc.d/static_arp for a while now, but the
v6 counterpart is missing: I'd call it static_ndp.

So I took rc.d/static_arp and patched it. ndp does not know about
-S (deleting old entry first), so I've just changed it to -s. Maybe
someone is able to add -S to ndp, otherwise one should add -d line
before -s.

rc.conf works the same way:

static_ndp_pairs="gateway"
static_ndp_gateway="2001:db8:120:9260::1 00:26:ff:ff:ff:ff"

It seems this "hack" is needed for the native v6 connectity provided
by Hetzner (German hosting provider).
