libtraceevent: Round up in tep_print_event() time precision
When testing the output of the old trace-cmd compared to the one that uses the updated tep_print_event() logic, it was different in that the time stamp precision in the old format would round up to the nearest precision, where as the new logic truncates. Bring back the old method of rounding up.
