test/Object is not correct place to have tests that check obj2yaml
functionality, because we have test/tools/obj2yaml folder for that.
In this patch I merged a few test cases with their YAMLs from Inputs
folder, converted one of binary inputs and moved them to
tools/obj2yaml folder.
There are still another tests that might need the same, so it is initial step.
My motivation was that I was able to damage a code responding for dumping/reading
group sections and no tests in yaml2obj/ob2yaml failed, what was really
confusing to see.
What exactly is broken about the relocation? It's valid for some kinds of relocations to have no symbol.
I think this test needs renaming and the comment updating.
