ipconfig: send host-name in DHCP requests

Normally dhclient can be configured to send the "host-name" option
in DHCP requests to update the client's DNS record. However for an
NFSROOT system, dhclient shall never be called (which may change the
IP addr and therefore lose your root NFS mount connection).

So enable updating the DNS record with kernel parameter

ip=::::$HOST_NAME::dhcp
