Wrong binaries in arm64 K3d image

[Sven Pfennig]

Problem description:

With the 0.9.0 release, a K3d image has been created with two supported platforms, linux/amd64 and linux/arm64, both images contain the same shim binaries (x86-64). Using the linux/arm64 leads to this error when creating a container with those shims:

Failed to create pod sandbox: rpc error: code = 
  Unknown desc = failed  to create containerd task: 
    failed to start shim: start failed: : 
      fork/exec /bin/containerd-shim-spin-v1: exec format error: unknown 

Additional info:

root@kwasm-debug-6npz6:/# uname -m
aarch64

root@kwasm-debug-6npz6:/# file /mnt/node-root/bin/containerd-shim-spin-v1 
/mnt/node-root/bin/containerd-shim-spin-v1: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), static-pie linked, with debug_info, not stripped

The arm64 image works only on MacOS with Docker Desktop since it is able to run x86_64 binaries in aarch64 images.
