* Make dir for babel --out-file
Currently there's unexpected regression after upgrade from babel 6.
On creating file with any depth like dist/index.js the error about
not existing directory is thrown.
In this diff I modified babel-cli to create deep directory for out-file
command.
I also replaced `mkdirp` with more supported `make-dir` package which
also have official promise support.
* Fix test
