make insert_data take an "unsigned long long" offset

When using genimage on a 32 bit host and trying to populate a ~8GiB
eMMC with a GPT image, we hit

INFO: hdimage(/dev/mmcblk0): determined size of block device /dev/mmcblk0 to be 7820083200
...
ERROR: hdimage(/dev/mmcblk0): seek /dev/mmcblk0: Invalid argument
ERROR: hdimage(/dev/mmcblk0): failed to write backup GPT table

This is because the "image->size - GPT_SECTORS*512" aka 7820066304
passed from hdimage_insert_gpt() becomes -769868288 when shoehorned
into a "signed long".

Make the offset parameter "unsigned long long" to match the protoype
of insert_image().
