Recursively creates the directory at the provided path. If the
directory already exists, no error is returned. All parents must
be valid directories (not files).
Example:
```javascript
// Default empty filesystem
sh.mkdirp('/test/mkdirp', function(err) {
if(err) throw err;
// the root '/' now contains a directory 'test' containing the directory 'mkdirp'
});
```
