perf tests: Add valid callback for parse-events test
Adding optional 'valid' callback for events tests in parse-events
object, so we don't try to parse PMUs, which are not supported.
Following line is displayed for skipped test:
running test 52 'intel_pt//u'... SKIP
Committer note:
Use named initializers in the struct evlist_test variable to avoid
breaking the build on centos:5, 6 and others with a similar gcc:
cc1: warnings being treated as errors
tests/parse-events.c: In function 'test_pmu_events':
tests/parse-events.c:1817: error: missing initializer
tests/parse-events.c:1817: error: (near initialization for 'e.type')
