perf script: hook up perf_scripting_context->pevent
Running the check-perf-trace scripts causes segfaults in both the Perl
and Python cases:
# perf script record check-perf-trace
# perf script -s libexec/perf-core/scripts/python/check-perf-trace.py
trace_begin
Segmentation fault (core dumped)
The reason is that the 'pevent' field was added to
perf_scripting_context but it wasn't hooked up with an actual pevent in
either case, so when one of the 'common' fields is accessed (in
util/trace-event-parse.c:get_common_fields()), pevent->events tries to
dereference a NULL pointer.
This sets the pevent field when the scripting context is set up.
