sstatesig: Include all dependencies in SPDX task signatures

Browse Source 
SDPX generation involves looking through BB_TASKDEPDATA for
dependencies, then linking to the generated documents for those
dependencies. These document links use a checksum to validate the
document, which means that if a upstream document changes, all
downstream documents must be regenerated to get the new checksum,
otherwise the compendium of documents produced by the build will have
broken links; therefore all dependent task should be included in the
signature (even from "ABI safe" recipes).
