[libvirt] [PATCH] Fix serial console telnet protocol support

[Mark McLoughlin]

With e.g.:

  <serial type='tcp'>
    <source mode='bind' host='127.0.0.1' service='4444'/>
    <protocol type='telnet'/>
    <target port='0'/>
  </serial>

You currently get:

  Unknown option: listen
  qemu: could not open serial device 'telnet:127.0.0.1:4444,listen'

With the telnet protocol, qemu expects "server" as an option
rather than "listen".
