[llvm] [Windows] Avoid crash calling remove_directories() (PR #118677)

[Dmitry Vasilyev via llvm-commits]

https://github.com/slydiman created https://github.com/llvm/llvm-project/pull/118677

We faced an unexpected crash in SHELL32_CallFileCopyHooks() on the buildbot [lldb-remote-linux-win](https://lab.llvm.org/staging/#/builders/197/builds/1066). The host is Windows Server 2022 w/o any 3rd party shell extensions. See #118032 for more details.
