b9c113af754540341d9529532fbadb7525168102 util: Avoid buggy std::filesystem:::create_directories() call (Hennadii Stepanov)

Pull request description:

  Compiled with some libstdc++ versions (e.g., on Ubuntu 20.04) [`std::filesystem:::create_directories()`](https://en.cppreference.com/w/cpp/filesystem/create_directory) call [fails](https://github.com/bitcoin/bitcoin/issues/24257#issue-1123753243) to handle symbol links properly.

  No behavior change in comparison to the [pre-20744](c194293883) master branch.

  Fixes bitcoin/bitcoin#24257.
