Temporarily enhance em(4) and igb(4) hack to take account for IFF_NOARP.
Without this changeset there will be no way to prevent these NICs from
sending ARP, which is harmful in server farms that is configured as
"Direct Server Return" behind a load balancer.

A better fix would remove the whole hack completely but it would be
later than 8.0-RELEASE.
