tools lib traceevent: Print event name when show warning if possible
It's sometimes useful to know where the parse failure was occurred. Add
do_warning_event() macro to see the failing event.
It now shows the messages like below:
$ perf test 5
5: parse events tests : Warning: [kvmmmu:kvm_mmu_get_page] bad op token {
Warning: [kvmmmu:kvm_mmu_sync_page] bad op token {
