selftests/powerpc/pmu: Add selftest for blacklist events check in power9

Browse source

Some of the events are blacklisted in power9. The list of blacklisted
events are noted in power9-events-list.h When trying to do event open
for any of these blacklisted event will cause a failure. Testcase
ensures that using blacklisted events will cause event_open to fail in
power9. This test is only applicable on power9 DD2.1 and DD2.2 and hence
test adds checks to skip on other platforms.
