[dualtor][route_check] filter out soc_ipv6 (#2899)

What I did
Skip soc_ipv6 when comparing appl_db and asic_db route entries on active-active dualtor. Because it's creating false alarms when tunnel route is added for soc ips. The route is meant to be programmed in asic only.

How I did it
How to verify it
Run the updated script on active-active dualtor devices.
