perf test: Fix ratio_to_prev event parsing test

test__ratio_to_prev() assumed the first event in a group is the leader,
which is not the case when the event is expanded into two event groups
on hybrid PMU's with auto counter reload support. Instead, iterate over the
event group generated for each core PMU. Also update "wrong leader" test to
check that the subordinate event has the correct leader instead of checking
that it is not the group leader. Finally, do not exit immediately if a PMU
without auto counter reload support is found.
