[PATCH openbmc v6 04/18] image_types_uboot: Don't truncate when assembling flash

[OpenBMC Patches]

From: "Milton D. Miller II" <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.
