    M llvm/test/tools/yaml2obj/ELF/section-type.yaml

  Log Message:
  -----------
  [yaml2obj] Don't use uninitialized Type (#123274)

Alternative to #123137

With -DMACHINE=EM_NONE, machine specific
sections, like SHT_ARM_EXIDX, will fall to parse
and set `Type`.

This triggers msan on
```
yaml2obj llvm-project/llvm/test/tools/yaml2obj/ELF/mips-abi-flags.yaml -DMACHINE=EM_NONE
```
