lib/spdx30_tasks: support directories deployed by image recipes

create_image_spdx() implementation assumes that image is indeed a file.
If image recipe deploys a directory (for example, which contains an
hierarchy of flash artifacts, that is used by SoC vendor-specific
flashing tool) which follows ${IMAGE_NAME}.${IMAGE_TYPE} naming scheme,
create_image_spdx() function will fail after trying to hash a directory:

*** 0002:do_create_image_spdx(d)
