Why I did it
In t1-topology, we frequently see the ndppd use a lot of CPU usage.
How I did it
Make the route-ttl setting correctly generate inside the /etc/ndppd.conf of swss container.
How to verify it
Run the test_cpu_memory_usage.py for multiple times and make sure the ndppd will not fail the test.
