Don't update the host-name field in dhclient.conf when not hardcoded.

On Debian and Ubuntu, the default host-name field in dhclient.conf is set to either "<hostname>" or "gethostname()" both of which get replaced by the machine's hostname at query time. The sed call currently present in lxc-clone hardcodes the hostname in dhclient.conf, causing dpkg to prompt on isc-dhcp updates. Signed-off-by: 's avatarStéphane Graber <stgraber@ubuntu.com>
