Bug#711799: PXE error: no server is specified

[Steven Chamberlain]

Okay, that turned out to be the grub-mkimage I was using, not the actual
GRUB2 modules.

We're now back to seeing the original problems from
https://bugs.debian.org/711799#14:
> * no DHCP-assigned network settings copied in from the PXE environment
> * no TFTP server IP copied in from the PXE environment

and as a result, not being able to fetch grub.cfg
