Remove NSUPDATE patch for dhcp package

After discussion with Eslimi, this patch disables DDNS on dhclient,
as the network port 2105 used by dhclient conflicts with thesame port
used on mtcClient. Now we change the port used by mtcClient from 2105
to 2118, then we can remove this patch.

Deployment test pass.
