Norway: More missing Riksveier...

[michih]

...but I have no evidence that they are really signed because GSV is out-dated (older than Rv/Fv changes). However, if other Rv routes are indicated on vegvesen.no and GSV from 2016 is available, I could always find signs. If that's not enough, we should keep this thread open till GSV is updated.
