LOG: [clang][DebugInfo][test] Set -fuse-lld for test matching linker invocation. (#190291)

This test doesn't work as intended when an alternative default linker is
specified via `-DCLANG_DEFAULT_LINKER=ld`. If this test isn't intended
to support alternate default linker, lmk I can just change the
downstream usage I'm seeing, though I figure other folks may have
similar configurations. Repro:

```
cmake -S llvm -B build -DLLVM_ENABLE_PROJECTS="clang" -DCLANG_DEFAULT_LINKER=ld -GNinja
ninja -C build
./build/bin/llvm-lit -v clang/test/DebugInfo/CXX/hotpatch.cpp

...

possible intended match
# |             6:  "/usr/bin/ld" "-out:hotpatch.exe" "-libpath:lib/amd64" "-libpath:atlmfc/lib/amd64" "-nologo" "-functionpadmin" "/tmp/lit-tmp-o7x0r1o_/hotpatch-4595de.obj" 
```

afaict it passed before because `-mincremental-linker-compatible` was
being used until e97a42d5f9fe51de50aabd4d9bf6874a4955f9fa, which would
match on the compilation line.
