Add test cases that exercise the scenario where an IPv6 nexthop is
replaced with an IPv4 nexthop while being part of a group. The group's
has_v4 flag must be updated so that subsequent IPv6 route additions are
properly rejected.
Two cases are covered:
1. Gateway nexthop replaced across families with an existing IPv6
route on the group (rejected by fib6_check_nh_list).
2. Blackhole nexthop replaced across families with no existing IPv6
route on the group (fib6_check_nh_list returns early) — this is
the path that triggers a NULL ptr deref without the kernel fix.
