Title: Fix issue #38 - Add a SystemUpdateID property

As we decided not to implement parallelism in async calls to upnp services, I am making the call serialized at the end of the current chain.

I decided to make the new async call at the end of the chain rather than at the begining because I would have had to move more context knowledge that is currently implemented in both msu_device_get_all_props() and msu_device_get_prop().

I still needed some context knownledge in my implementation because the same prv_get_system_update_id() function may be called from several different contexts (MSU_TASK_GET_ALL_PROPS / MSU_TASK_GET_PROP / MSU_TASK_GET_RESOURCE).
