virt: setup TCP chardevice in libvirt driver

Setup the tcp chardevice in the libvirt driver based on the
configuration (if the serial consoles are enabled) and disable the
logging to a file since we have an interactive console.

A new image property is introduced: hw_serial_port_count
A new flavor extra spec is introduced: hw:serial_port_count
