Daniel Bristot de Oliveira 0e47b38dcd tools lib traceevent: Implement '%' operation
The operation '%' is not implemented on event-parse.c, causing an error
when parsing events with '%' the operation in its printk format. For
example,

  # perf record -e sched:sched_deadline_yield ~/yield-test
    Warning: [sched:sched_deadline_yield] unknown op '%'
  ....
  # perf script
    Warning: [sched:sched_deadline_yield] unknown op '%'
        test  1641 [006]  3364.109319: sched:sched_deadline_yield: \
                        [FAILED TO PARSE] now=3364109314595        \
                        deadline=3364139295135 runtime=19975597

This patch implements the '%' operation. With this patch, we see the
correct output:

  # perf record -e sched:sched_deadline_yield ~/yield-test
    No Warning

  # perf script
        yield-test  4005 [001]  4623.650978: sched:sched_deadline_yield: \
                now=4623.650974050                                       \
                deadline=4623.680957364 remaining_runtime=19979611
