build: update build scripts to support Node.js v16

Node.js v16's `fs.rmdirSync` will now throw an `ENOENT` error if the path does not exist. `fs.rmSync` is now the preferred option when using Node.js v16 but since this function is not available on Node.js v12 both are tried with `fs.rmSync` given preference.
