dhcp: correct leases directory location
dhcp: correct leases directory location

The DHCP client currently expects to be able to create a leases file in
"/var/lib/dhcp" as configured in dhcp3.inc. Recipe is currently creating a
directory called "/var/lib/dhcp3", resulting in the following error:

can't create /var/lib/dhcp/dhclient.eth0.leases

Correct directory naming to resolve error.
