virt: Register "its" as class property
Class properties make QOM introspection simpler and easier, as
they don't require an object to be instantiated.
Note: "its" is currently registered conditionally, but this makes
the feature be registered unconditionally. The only side effect
is that it will be now possible to set its=on on virt-2.7 and
older.
