[PATCH openbmc 01/16] image_types_uboot: Don't truncate when assembling flash

From: Milton Miller <miltonm at us.ibm.com>

The generate_flash_image step was creating a file then using dd to
fill in the pieces, but missed adding the conv=notrunc flag, so each
step was shortening the file to its output.

Add the forgotten conversion flag to each dd command.
