Subject: [PATCH] Fix container start failure on Pi: disable cgroup swap limit

Raspberry Pi OS does not enable swap accounting in cgroups by default,
so the memory.swap.max cgroup v2 file does not exist.  Setting --memory
without --memory-swap causes runc to write a swap limit to that file,
which fails with ENOENT.

Adding --memory-swap=-1 tells runc to leave swap unlimited, skipping
the memory.swap.max write entirely.
