This patch adds the possibility to run commands using the default parameter
in 'lkvm sandbox'. For example, a user would now be able to run:
'lkvm sandbox firefox'
And have a sandboxed firefox instance start in the guest.
For commands with parameters, we still need to use dashdash to pass the
parameters (similar to 'git bisect run'). For example:
'lkvm sandbox -- ls -al /bin
