archs38: Reduce generalization

As support of ARC HS38 in OpenWRT/Lede matures we don't need
debug-only output binaries any longer, so purging vmlinux for
AXS10x boards.

As for uImage for nSIM it makes completely no sense because there's no
way to run U-Boot on nSIM.

So we remove add_archs38_XXX scripts making code more compact and
cleaner.
