selftests/bpf: validate struct_ops early failure detection logic

Browse source

Add a simple test that validates that libbpf will reject isolated
struct_ops program early with helpful warning message.

Also validate that explicit use of such BPF program through BPF skeleton
after BPF object is open won't trigger any warnings.
