Every binary that can trigger tracepoints should have the module_call_init().
I'd done it for emulators, qemu-img, qemu-nbd, and qemu-io. I could tell
which need it, since they're the ones that need to link to the trace.o
files, otherwise you'll unresolved symbol errors. So I think what I have
is correct.
