use proper RapidJSON API in qcnl

[olafhering]

According to the way RapidJSON is used elsewhere in the repository (at e880e54), and how it is documented at rapidjson.org, the intended API appears to be:

#include <rapidjson/*.h>

I think this change is required, and the additional RapidJSON related include need to be adjusted in the Makefile:
