Also add a helper executable that implements the check for Hyper-V
(like ConditionVirtualization=microsoft in the systemd units).
(cherry picked from commit 50747480c882dae7d3c8f7b4d0df5cf3276c4ee5)
This was originally added to debian/copyright in src:linux-2.6, which
was the source for linux-tools binary packages. Obviously it belongs
in src:linux-tools now.
