[tools] testbot/LibvirtTool: Always use a default deadline if none is set.

[Francois Gouget]

VM->ChildDeadline may be unset not only while in debug mode if the VM
is in maintenance mode, but also if another VM sharing the same
hypervisor domain is in maintenance mode.
So rather than relying on the VM status, just use a default value as a
fallback.
