tools lib traceevent: Add const qualifier to string arguments

Browse Source 
If pevent_register_event_handler() received a string literal as
@sys_name or @event_name parameter, it emitted a warning about const
qualifier removal.  Since they're not modified in the function we can
make it have const qualifier.
