dm: acrn-tool: Add del runC configuration in acrnctl del

Browse Source 
The patch adds logic to delete runC configuration in acrnctl del command.
After launch the VM in container there will have configuration files in user
directory. When delete the VM by "acrnctl del" command the command will delete
the runC configuration files at same time.
