tracing/events: Move TRACE_SYSTEM outside of include guard
If TRACE_INCLDUE_FILE is defined, <trace/events/TRACE_INCLUDE_FILE.h>
will be included and compiled, otherwise it will be
<trace/events/TRACE_SYSTEM.h>
So TRACE_SYSTEM should be defined outside of #if proctection,
just like TRACE_INCLUDE_FILE.
Imaging this scenario:
#include <trace/events/foo.h>
-> TRACE_SYSTEM == foo
...
#include <trace/events/bar.h>
-> TRACE_SYSTEM == bar
...
#define CREATE_TRACE_POINTS
#include <trace/events/foo.h>
-> TRACE_SYSTEM == bar !!!
and then bar.h will be included and compiled.
