selftests: fib_nexthops: Test large scale nexthop flushing 



Test that all the nexthops are flushed when a multi-part nexthop dump is
required for the flushing.

Without previous patch:

 # ./fib_nexthops.sh
 TEST: Large scale nexthop flushing                                  [FAIL]

With previous patch:

 # ./fib_nexthops.sh
 TEST: Large scale nexthop flushing                                  [ OK ]
