tracing: Include module.h in define_trace.h



While doing some developing, Peter Zijlstra and I have found
that if a CREATE_TRACE_POINTS include is done before module.h
is included, it can break the build.

We have been lucky so far that this has not broke the build
since module.h is included in almost everything.
