Start on DOWN interfaces
Do not skip interfaces during startup because they're not UP.
dhcpd(8) can start listening on such interfaces just fine (given suitable
IPs on them) and interfaces may come UP later in time.
Otherwise dhcpd would fail to start completely if it didn't find any
interface that would be UP early on and administrators had to restart dhcpd.
Other daemons and nc(1)'s `-l' listen just fine on DOWN interfaces as well.
Noticed while switching a bridge(4)/vether(4) setup to veb(4)/vport(4) and
hostname.vport without explicit "up" (vport does not implicitly pulls itself
UP when configuring an address).
