copyImgFiles failed when overlay has subfolders

[demin-han]

Use this workload: https://github.com/ucb-bar/coremark-workload put a "hello" subfolder to overlay

Fail report: TaskError - taskid:/home/FireMarshal/images/firechip/coremark/coremark.img PythonAction Error Traceback (most recent call last): File "/home/miniforge3/envs/firemarshal/lib/python3.10/site-packages/doit/action.py", line 461, in execute returned_value = self.py_callable(*self.args, **kwargs) File "/home/FireMarshal/wlutil/build.py", line 603, in makeImage wlutil.applyOverlay(config['img'], config['overlay']) File "/home/FireMarshal/wlutil/wlutil.py", line 753, in applyOverlay copyImgFiles(img, flist, 'in') File "/home/FireMarshal/wlutil/wlutil.py", line 727, in copyImgFiles perms = int(oct(os.stat(dirPath).st_mode)[-3:], 8) FileNotFoundError: [Errno 2] No such file or directory: '/home/FireMarshal/disk-mount/hello'

ERROR: Failed to build workload coremark.json

I think this issue related to Commit c510768.

when check and change permission, the subfolder is still not exist.
