[Windows] Remove prefix "rancher-wins" when collecting antrea-agent logs

After switching to Containerd runtime, Antrea doesn't depend on rancher-wins
when running agent. So the agent log files should start with "antrea-agent".

Remove the prefix "rancher-wins" in the file name filters when collecting agent
logs on Windows.
