kernel - Fix mbuf header exhaustion w/ degenerate unix domain socket case
* Increase the number of mbuf headers to accomodate a degenerate
fd-passing case with chains of unix domain sockets, one fd per
socket.
* This does not address other mbuf exhaustion issues which can crop
up in a user ddos attack due to the default number of fds a user
is allowed to own.
