When llvm-copy removes `.dwo` sections the index of symbol table,
the indices of the symbols and the indices of the sections which go
after the removed ones changes. That affects on SHT_GROUP sections,
which needs to be updated.

Initially this test used a precompiled object, I rewrote it to use YAML
and improved a bit.
