[elbe-users] add binary files to target image

[Christian Baur]

Thank you for the suggestion, but i found another way to do it which 
does involve less steps to perform:

With "elbe chg_archive" a directory of the host is attached as archive 
to the XML file and then unpacked by elbe to the target rfs.

This is outlined in the ELBE documentation:
The second diagram from the ELBE Overview chapter shows the steps 
performed inside the build VM 
(https://elbe-rfs.org/docs/sphinx/article-elbeoverview-en.html).

Question:
The step "unpack config archive" is done twice!?
Is this correct and what is the purpose of doing it a second time?
