dep: remove mkdirp dependency

* dep: mkdirp hasn't been updated in 4 years, and node's fs library
has had a recursive option for `fs` since v10.12 (oldest active LTS
version). Additionally `mkdirp` depends on a version of library `minimist` that has a minor vulnerability associated.

* https://npmjs.com/advisories/1179
