[llvm] [BOLT,test] Add missing pipe in dwarf5-debug-names-skip-forward-decl.s (PR #226338)

[Fangrui Song via llvm-commits]

https://github.com/MaskRay created https://github.com/llvm/llvm-project/pull/226338

With cl::Grouping, --check-prefix=POSTCHECK parses as -c -h..., so
llvm-dwarfdump prints --help and exits 0, and the checks never run.
