perf record: Support aarch64 random socket_id assignment
Same as in the commit 01766229533f ("perf record: Support s390 random
socket_id assignment"), aarch64 also have this problem.
Without this fix:
[root@localhost perf]# ./perf report --header -I -v
...
socket_id number is too big.You may need to upgrade the perf tool.
