selftests/bpf: Test case for lacking CFI stub functions.
Ensure struct_ops rejects the registration of struct_ops types without
proper CFI stub functions.
bpf_test_no_cfi.ko is a module that attempts to register a struct_ops type
called "bpf_test_no_cfi_ops" with cfi_stubs of NULL and non-NULL value.
The NULL one should fail, and the non-NULL one should succeed. The module
can only be loaded successfully if these registrations yield the expected
results.
