perf test: Skip metric w/o event name on arm64 in stat STD output linter

stat+std_output.sh test fails on my arm64 machine:
[root@localhost shell]# ./stat+std_output.sh
Checking STD output: no args Unknown event name in TopDownL1                 #     0.18 retiring
[root@localhost shell]# ./stat+std_output.sh
Checking STD output: no args [Success]
Checking STD output: system wide [Success]
Checking STD output: interval [Success]
Checking STD output: per thread Unknown event name in tmux: server-1114960                                                   #     0.41 frontend_bound

When no args specified `perf stat` will add TopdownL1 metric group
and the output will be like:
[root@localhost shell]# perf stat -- stress-ng --vm 1 --timeout 1
stress-ng: info:  [3351733] setting to a 1 second run per stressor
stress-ng: info:  [3351733] dispatching hogs: 1 vm
stress-ng: info:  [3351733] successful run completed in 1.02s

Metrics in group TopDownL1 don't have event name on arm64 but are not
listed in the $skip_metric list which they should be listed. Add them
to the skip list as what does for x86 platforms in [1].
