That result code is mapped directly to the result code for the command line function hab_auth_img - which means when hab_auth_img succeeds it is returning CMD_RET_FAILURE (1) instead of CMD_RET_SUCCESS (0). This patch fixes this behaviour by making authenticate_image() return 0 for success and 1 for failure. Both users of authenticate_image() as a result have some minimal churn. The upshot is once done when hab_auth_img is called from the command line we set $? in the standard way for scripting functions to act on.
