utils: ipc: Use the proper namespace for mojom structs

Browse source 
Structs defined in mojom previously used the namespace of the mojom file
that was being used as the source. This is obviously not the correct
namespace for structs that are defined in core.mojom. Fix the jinja
function for getting the element type including namespace, and use it.
