Do not use "nodhcp" bootoption anymore, since recent ISOs have new way of network...

With integration of recent live-boot versions we don't have DHCP
requests in grml-autoconfig anymore (which used to require the
nodhcp option to disable the request) but the initrd cares about
it. If we're using nodhcp for booting then the initrd won't
configure networking any longer at all, which means booting via
PXE doesn't work.

To make sure that the nodhcp bootoption isn't present in custom
live systems let's remove the option using grml2usb's
--remove-bootoption=nodhcp feature (grml2usb ftw!).
