perf kvm: Add skip_event() for --duration option
Current code skips output of the x86 specific HLT event in order to
avoid flooding the output with enabled --duration option. The events to
be skipped should be architecture dependent, though.
Let's add an architecture specific array of events to be skipped and
introduce a skip_event() function checking against that array.
