Fix QOS tests to run on 64p topo

[arista-nwolfe]

64 port topos like topo_t2_single_node_max_64p and topo_t2_single_node_max_64p_v2 won't run qos/test_qos_sai.py because the skip conditionals explicitly call out the topology names:

topo_name not in (constants['QOS_SAI_TOPO'] + ['t2_single_node_max', 't2_single_node_min'])

This change will group any topo with t2_single_node* in the condition.

Also fixing an issue where we used the wrong system_port key on single-asic VOQ systems.
Without this we see the following failures:

>           wredProfileName = "WRED_PROFILE|" + six.text_type(dut_asic.run_redis_cmd(
                argv=[
                    "redis-cli", "-n", "4", "HGET",
                    "{0}|{1}|{2}".format(table, port, self.TARGET_QUEUE_WRED),
                    "wred_profile"
                ]
            )[0])
E           IndexError: list index out of range

It's trying to read the key QUEUE|Ethernet0|3 when it should be QUEUE|ctn101|Asic0|Ethernet0|3.
I believe this was an oversight when #20544 was added (only supports multi_asic).
Instead the conditional should've been more like #7823 and hardcode the Asic0 in the case of single-asic systems.
