backup export will override 'root'-files if multiple folders, given in cfg, containing 'root'-files with same name

[michmue]

Exporting multiple files with same name into one root folder will override them.
Current code only has temporary workaround for specific Policy exports case.

• workaround: don't multiple folder entires in config for one app which have same filenames in there root location
• fix1: check for multiple filenames beforehand -> get der parent folder name -> create subfolders in app backup location
• fix2 (simple): always create subfolders with name of last folder given in each folders entries
