rust: qdev: expose inherited methods to subclasses of SysBusDevice

The ObjectDeref trait now provides all the magic that is required to fake
inheritance.  Replace the "impl SysBusDevice" block of qemu_api::sysbus
with a trait, so that sysbus_init_irq() can be invoked as "self.init_irq()"
without any intermediate upcast.
