As far as I can tell, SCLP_EVENT_CTRL_PGM_ID is an *SCLP* event only, but 
you're trying to wait for a *QAPI* event here instead. That's two completely 
different things, SCLP events are something between the guest and QEMU, 
while QAPI events are between QEMU and the monitoring program (i.e. in this 
case the test).

If you want that QEMU generates such QAPI events for the monitoring program, 
you have to do something similar to commit 1cfe52b78240679 and add the 
qapi_event_send_... function to the right spot in your code.
