perf tools: Fix auto-complete on aarch64
On aarch64 CPU related events are not under event_source/devices/cpu/events,
they're under event_source/devices/armv8_pmuv3_0/events on my machine.
Using current auto-complete script will generate below error:
[root@localhost bin]# perf stat -e
ls: cannot access '/sys/bus/event_source/devices/cpu/events': No such file or directory
Fix this by not testing /sys/bus/event_source/devices/cpu/events on
aarch64 machine.
Fixes: 74cd5815d9af6e6c ("perf tool: Improve bash command line auto-complete for multiple events with comma")
