perf stat: Update event skip condition for system-wide per-thread mode and merged uncore and hybrid events

In print_counter_aggrdata(), it skips some events that has no aggregate
count.  It's actually for system-wide per-thread mode and merged uncore
and hybrid events.

Let's update the condition to check them explicitly.

Fixes: 91f85f98 ("perf stat: Display event stats using aggr counts")
