btrfs_turris1x: add back section to import medkit to factory snapshots
For some users, who have Turris 1.x, it could be problematic to use the migration process, which might take some time. Provide steps how they can download medkit and flash it to factory snapshots once they have Btrfs on their router.
It was requested by our support department to bring it back.
