Strange route selection (defroute and specific)

Hello Nico,

That's a bug in BIRD 3 CLI, apparently. In BIRD 2, we actually display
just the longest prefix match, here we display all routes which could
match.

The actual route selection is not affected in any way by this.

Gonna fix that, so that you get the LPM view back again. Sorry and
thanks for reporting.
