Subject: [PATCH] Replace mkdirp with builtin recursive flag

In node 10.12 mkdir got new recursive flag which provides the same
functionality as mkdirp.

See here https://nodejs.org/api/fs.html#fs_fs_mkdir_path_options_callback

Also node 10 got builtin promisified `fs` utilities.

See here https://nodejs.org/api/fs.html#fs_fs_promises_api
