[Autotest] [PATCH 2/2 v4] client.shared.based_utils:Make and copy the src dir to client/tmp/≤test>/

Currently, the src dir may be removed when the test version has changed.
Just to check to make and copy the src if it has been removed.

After check the src dir , patch files need to be copied to the parent
of src dir
