Don't kill sdcards with boot_tries

Don't kill sdcards with boot_tries

USB/SDCard boot devices typicaly don't run software updater,
and won't have success ever set. We never want to try to
fall back to the empty B partition either. The workaround
for this is to set the successful bit regardless of actual
boot success.

One change, then LGTM.

build_image:656: cgpt add -i 2 -S 1 "${OUTPUT_DIR}/${image_name}"
Should be:

$GPT add -i 2 -S 1 "${OUTPUT_DIR}/${image_name}"

The $GPT variable is set by local_gpt() at the beginning of this script, to
point to the latest and correct cgpt utility.
