kill dhclient before starting a new instance
Currently, if you're re-routed to the beginning of the install process or to the beginning of the netconfig process, subsequent attempts to configure via dhclient will fail as dhclient is already running.
Since there are many ways to get into this state, we should kill any dhclients prior to configuring the primary interface with dhcp.
Tested on FreeBSD 10.2-STABLE amd64.
