Brunnel changes in transportation and transportation_name layers (#1027)

Browse Source 
https://github.com/openmaptiles/openmaptiles/issues/999

- Point 1 solved only partially - there is `brunnel` value added into zooms 9, 10, 11. For zooms 8 and smaller it would need change in osm_transportation_merge_ tables - I am going to try it but maybe its SQL costs will be to high.

- Point 2 solved.
