perf evlist: Extend arch_evsel__must_be_in_group to support hybrid systems
For the hybrid system, the "slots" event changes to "cpu_core/slots/", need
extend API arch_evsel__must_be_in_group() to support hybrid systems.
In the origin code, for hybrid system event "cpu_core/slots/", the output
of the API arch_evsel__must_be_in_group() is "false" (in fact,it should be
"true"). Currently only one API evsel__remove_from_group() calls it. In
evsel__remove_from_group(), it adds the second condition to check, so the
output of evsel__remove_from_group() still is correct. That's the reason
why there isn't an instant error. I'd like to fix the issue found in API
arch_evsel__must_be_in_group() in case someone else using the function in
the other place.
