selftests: fib_nexthops: Add test cases for FDB status change 



Add the following test cases for both IPv4 and IPv6:

* Can change from FDB nexthop to non-FDB nexthop and vice versa.
* Can change FDB nexthop address while in a group.
* Cannot change from FDB nexthop to non-FDB nexthop and vice versa while
  in a group.

Output without "nexthop: Forbid FDB status change while nexthop is in a
group":
