perf test: Fix parse events test to follow proper raw event name

perf test: Fix parse events test to follow proper raw event name

Following commit changed raw event names to carry event modificator.

  perf evsel: Reconstruct raw event with modifiers from perf_event_attr
  commit 6eef3d9c2bcf52b7a3c18e609f5838c007b989a4
  Author: Arnaldo Carvalho de Melo <acme@redhat.com>

The perf_evsel__name function now returns ':mod' suffix for raw events,
so we need to follow that in current tests.

All tests pass now for 'perf test parse' suite.
