tracing/stat: replace trace_stat_session by stat_session



The "trace" prefix in struct trace_stat_session type is annoying while
reading the trace_stat.c file. It makes the lines longer, and
is not that much useful to explain the sense of this type.

Just keep "struct stat_session" for this type.

[ Impact: make the code a bit more readable ]
