Fix texture orientation when placing nodes using on_place = minetest.rotate_node on walls or ceilings

- see  https://forum.minetest.net/viewtopic.php?f=6&t=10523
- Adjust the values of dirs1 and dirs2 so that rotate_and_place orients textures correctly
- According to doc/lua_api.txt if paramtype2 == "facedir" the two least significant bits of parm2 orient the texture around the axis. For dirs1 (looking at a wall) these would be 0, 1, 2, 3 and for dirs2 (looking at the ceiling) 2, 1, 0, 3
