qdev: Make qdev_get_machine() not use container_get()

Currently, qdev_get_machine() has a slight misuse on container_get(), as
the helper says "get a container" but in reality the goal is to get the
machine object.  It is still a "container" but not strictly.

Note that it _may_ get a container (at "/machine") in our current unit test
of test-qdev-global-props.c before all these changes, but it's probably
unexpected and worked by accident.

Switch to an explicit object_resolve_path_component(), with a side benefit
that qdev_get_machine() can happen a lot, and we don't need to split the
string ("/machine") every time.  This also paves way for making the helper
container_get() never try to return a non-container at all.
