[llvm] [CI][ScriptedBuilder] Avoid python 3.12-only option (PR #181746)

[Michael Kruse via llvm-commits]

https://github.com/Meinersbur created https://github.com/llvm/llvm-project/pull/181746

The shutil.rmtree(onexc=) parameter was only added in Python 3.12. Use onerror= instead whose callback signature takes a different third parameter which is ignored anyway.
