[llvm] [BOLT][test] Fix 'dump-dot-func' test execution on Windows host. (PR #155522)

[Vladimir Vereschaka via llvm-commits]

https://github.com/vvereschaka created https://github.com/llvm/llvm-project/pull/155522

Replaced non-existent %clang++ substitute with %clangxx. %clang++ gets became `clang.exe++` on the Windows host that failures the test execution.
