tests/unit/test-smp-parse: QOM'ify smp_machine_class_init()

smp_machine_class_init() is the actual TypeInfo::class_init().
Declare it as such in smp_machine_info, and avoid to call it
manually in each test. Move smp_machine_info definition just
before we register the type to avoid a forward declaration.
