Add a space in show route output between AS number and origin

[Sébastien PARISOT]

Hello BIRD team!

This simple patch (for branch master) adds a space between the AS number and 
the route origin in show route output, I think this improves readability.

Example, current BIRD:
    10.0.0.0/8          unicast [blabla] * (100/210) [AS12322i]
And with the patch:
    10.0.0.0/8          unicast [blabla] * (100/210) [AS12322 i]

Thanks!
