Make carp(4) aware of its physical interface:

- If the physical interface goes down or the link goes down,
  the carp interface goes down as well.
- We treat this like the preemption holdoff with pfsync.
  So if one of the carp interfaces is known to be bad (because the
  physical interface it's associated with is bad), all the other carp
  interfaces back off: they won't preempt, and their advskew goes to 240.
