Subject: [PATCH] qbittorrent: add default trackerSearch option, include
 python3

Since people regularly open reports about tracker search not working because
python is not found.
And since Tracker Search in qBittorrent can not be disabled & at the same time
the Pythong is needed for it to work - including Python for default
functionality to work.
