Blocker during installing with installer

[hoyajigi]

What Operating System(s) are you seeing this problem on?

macos (aarch64)

Backend.AI version

latest

Describe the bug

When you install with https://bnd.ai/installer-stable-macos-aarch64, on code line

backend.ai/src/ai/backend/agent/docker/kernel.py

Line 613 in a620a8c

shutil.copyfile(proxy_worker_binary, "/tmp/backend.ai/linuxkit-metadata-proxy")

, you will get error like [Errno 2] No such file or directory: '/tmp/backend.ai/linuxkit-metadata-proxy' because there is no directory as /tmp/backend.ai.
you can fix it with mkdir -p /tmp/backend.ai but it would be hard to figure out.
