[BGP] Adapt NNCP routes to new nmstate version

PR [1] was included in nmstate-2.2.50-1, detecting and rejecting multiple
routes to a common destination with the following error:
```
InvalidArgument: Route to XXX has conflicting nexthop
(AAA; BBB). Either set the existing route to 'absent', or
set their 'weight' (for ECMP) or 'metric' value
```

Adding weights to those routes avoids this error.
