[PATCH] imx-image: Fix uninitialized add_barebox_header

It's set to 1 if the -b option is used, but is neither initialized nor
set to 0 if not.  Since the barebox image building recipies only uses -b
with this tool, it wasn't noticed.

Note that ommiting -b, so as to not add a barebox header, still adds a
1024 byte header, it's just blank.  I think it would be better if it was
not added at all.  If flashing to an SD card or eMMC main block, this
header overlaps the partition table, and so needs to not be flashed.
It's not part of the imx image.  It's just padding to place the imx
image at the correct location w.r.t. the start of flash.
