Revert r264907 and r264908:
Restore make-memstick.sh back to its original state to unbreak booting for machines that do not support GPT. I have in-progress work to keep the MBR layout and add the EFI partition, but it is not yet ready, and does need at least one full release build to be certain it does not break.
