[Cooker] Patch for ifup to fix problem where FQDN is passed to DHCP server

[john . allen]

If you are using the DHCP server to automatically update your DNS, and you
do not apply this patch, your DNS entries will be incorrect.

Before the patch I was getting
tornado.moyville.ie.moyville.ie

After the patch I get the correct entry
tornado.moyville.ie
