Minor bin/libs/fs.mkdirp update

[Martin-Zeithaml]

mkdirp is:

• always expecting input
• "Split loop" not working as expected, see test

Split loop test

function mkdirpOld(path) {
    let paths = [];
    let parts = path.split('/');
    let currentPath = '';
    parts.forEach((part)=> {
      currentPath+='/'+part;
      if (currentPath.startsWith('//')) {
        currentPath = currentPath.substring(1);
      }
      paths.push(currentPath);
    });
    console.log(paths);
}

function mkdirpNew(path) {
    let paths = [];
    let parts = path.split('/');
    let currentPath = '';
    parts.forEach((part)=> {
      if (part) {
        currentPath += '/' + part;
        paths.push(currentPath);
      }
    });
    console.log(paths);
}

mkdirpOld('/asdf/asdf////134////2435234524/////asdfasdfasd');

mkdirpNew('/asdf/asdf////134////2435234524/////asdfasdfasd');
