[PATCH v6 3/4] perf parse-events: Set is_pmu_core for legacy hardware events

[Ian Rogers]

Also set the CPU map to all online CPU maps. This is done so the
behavior of legacy hardware and hardware cache events better matches
that of sysfs and json events during
__perf_evlist__propagate_maps. Fix missing cpumap put in "Synthesize
attr update" test.
