[test] drop forsaken windmill test (Closes 2535376)
* not run since multiple years
* windmill itself is in poor shape not even packaged in Debian.
The peace which other seek they find;
The heaviest storms not longet last;
Heaven grants even to the guiltiest mind
An amnesty for what is past;
When will my sentence be reversed?
I only pray to know the worst;
And wish as if my heart would burst.
