The full debian dsc files of layer will be passed
to dsc_depend module to resolve the whole dependencies
for the target packages, so the packages in the layer
will be built in order.
Story: 2008846
Task: 45360
Test Plan:
Pass: build-pkgs -c -p <X>
Notes: '-c -a' will clean the cached list, otherwise
there may have the below harmless error:
'cache value should have dsc and checksum'
just ignore it.
Pass: build-pkgs -c -a
Pass: build-pkgs -c -l <layer>
Depends-On: https://review.opendev.org/c/starlingx/root/+/841063
