SeccompProfile errnoRet field is a string but should be a uint

[CoreyCook8]

What happened:

When trying to deploy a pod with a custom seccomp profile with a string I get
Warning Failed 45m (x8 over 47m) kubelet Error: setup seccomp: from field: load local profile: decoding seccomp profile failed: json: cannot unmarshal string into Go struct field Syscall.syscalls.errnoRet of type uint

What you expected to happen:

I expect the pod to be able to deploy with a custom errnoRet value specified.
The yaml from security-profiles-operator expects a string but requires a uint in the resulting json file.

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

Create a seccomp profile with an errnoRet value specified.
Try to deploy a container with that seccomp profile in the securityContext

Anything else we need to know?:

I can't see a reason to have the errnoRet be a string value so I think it just needs to be changed to a uint.

Environment:

• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release):
• Kernel (e.g. uname -a):
• Others:
