dhcpd: create dhcpd user for dhcp dameon 

This patch enables the functionality for dhcpd service to be started
with dhcp uid and gid.

Test steps:

Step 1: Assign ip to interface
ifconfig eth0 192.168.1.1

Step 2: Edit /etc/dhcp/dhcpd.conf:
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
subnet 192.168.1.0 netmask 255.255.255.0 {
        option broadcast-address 192.168.1.255;
        range 192.168.1.88 192.168.1.88;
        option routers 192.168.1.0;
}

Step 3: Edit /etc/default/dhcp-server:
INTERFACES="eth0"

Step 4: Check uid and gid of running dhcpd process
$ ps -eo user:19,group:19,cmd | grep dhcpd
dhcp        dhcp        /usr/sbin/dhcpd eth0 -user dhcp -group dhcp
