config_tools: fix the issue for debuild on tgl-rvp with hybrid scenario

The debian build rule of calculating method for post launch vm ids
when generating launch scripts should not be reading //vm/@id in
scenario xmls directly but reading //vm/@id in scenario xml and
then plus vm id for service vm.
Since the objective here is to generate the launch scripts for all
VMs, change the debian rule to invoking the launch_cfg_gen.py script
without parameter user_vmid when there are post launch vms to achieve
the objective.
