No ARM64 Support for Selinuxd

[KrisJohnstone]

What happened:

Enabled selinux:

kubectl -n security-profiles-operator patch spod spod --type=merge -p '{"spec":{"enableSelinux":true}}'

Upon pod restart the selinuxd container fails to start:

exec /usr/bin/bash: exec format error

If I pull the image from an ARM machine:

What you expected to happen:

Container to start successfully.

How to reproduce it (as minimally and precisely as possible):

On a cluster with ARM64 Nodes, enable selinux:

kubectl -n security-profiles-operator patch spod spod --type=merge -p '{"spec":{"enableSelinux":true}}'

Environment:

• Cloud provider or hardware configuration:
  EKS
• OS:
  AL2023
• Kernel (e.g. uname -a):
  6.12
