Currently, dummy archives are created for skipped sstate tasks. We relied
on these never being installed (the setscene task is missing) however this
leads to odd behaviour as for example the setscene stamps are never looked
at.
Rather than trying to continue with the two separate behaviours, really
skip package creation. We do need the file manipulation steps to install files
under sstate control from a manifest perspective so we only skip at the final
creation step.
