[KubeArmor] Supporting KubeArmor for ARM platforms

[nate-double-u]

KubeArmor has garnered interests from edge computing platforms (such as LF Edge OpenHorizon) that leverages k8s control plane for workload orchestration. The primary requirement is to support ARM platforms that are prevalent on the edge devices (especially Raspberry PI). KubeArmor leverages eBPF for observability and Linux Security Modules (such as AppArmor) for policy enforcement. One of the challenge is to check if the eBPF primitives such as observing kprobe, kretprobe, tracepoints that are typically available on the x86 platform are also available on the ARM platform and check if the parameter list fulfills the requirement. Post this analysis, the kubearmor code might have to be changed to accomodate any differences in the eBPF behaviour.
