[PATCH 1/3] git: reset our fork to OE upstream for re-forking

[Henning Schild <henning.schild@siemens.com>]

Note that this commit alone will not work. It is just to get back to a
starting point for clean history.

It takes the original file from our current OE version in this tree as
basis for later changes.
