Description of PR
test_lldp_neighbor_post_orchagent_reboot uses prefix restart_orchagent() to warm restart orchagent. This warm restart of orchagent(kill orchagent and restart orchagent process) is not supported on chassis with type VOQ.
Add code to handle chassis type VOQ case by restarting the swss@0(1) service. This will cause ports to be removed from lldp table and add back in so we can test the issue found in #6560.

For VOQ type chassis, uses "systemctl restart swss@0(1)" instead.
