lscpu: add configured state to output
CPUs may be in a configured or deconfigured state depending if the CPU resource
may be used by the guest. If a CPU is in configured state the guest may use it
(i.e. set it online). It it is in deconfigured state it cannot use it before
changing its state to configured. Display this CPU attribute as well.
