[PATCH] fix #6079: use vncticket endpoint for VM serial terminal

[Koji Nishimura <nsm.kkoji@gmail.com>]

Use the vncticket endpoint for the VM serial terminal termproxy path.

The node shell termproxy path already uses the vncticket endpoint,
but the VM serial terminal path still uses the older authentication
flow.

That older flow prevents VM /termproxy from working with API tokens,
because authentication fails before the websocket connection can use
the VNC ticket verification path.

Make the VM serial terminal path use the same vncticket-based
authentication flow as the node shell path.

This fixes the VM /termproxy side of bug 6079. In local testing,
this was required together with the already-posted access-control
change for token-owned VNC ticket verification.
