Add "fail_route_offload" flag to disallow offloading routes.
It is needed to test "offload failed" notifications.
Create the flag as part of nsim_fib_create() under fib directory and set
it to false by default.
When FIB_EVENT_ENTRY_{REPLACE, APPEND} are triggered and
"fail_route_offload" value is true, set the appropriate hardware flag to
make the kernel emit RTM_NEWROUTE notification with RTM_F_OFFLOAD_FAILED
flag.
