untar: mv store dirs into extract_file

[yuchen0cc]

What this PR does / why we need it:
Move store dirs into extract_file. (Directory mtimes must be handled at the end to avoid further file creation in them to modify the directory mtime)
This move will avoid aufs whiteout files (.wh..wh.aufs, .wh..wh.orph/, .wh..wh.plnk/) from creating and setting attributes.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
