config_tools: add logic for virtio_framework in launch script

Browse Source 
If the user select "Kernel based (Virtual Host)" in virtio_framework
entry, the "vhost" string will be added to the dm parameter.
The generated launch script will look like below:
"virtio-net tap=WaaG,vhost,mac_seed=${mac:0:17}-POST_STD_VM1"
