bpf: check bpf_dummy_struct_ops program params for test runs
When doing BPF_PROG_TEST_RUN for bpf_dummy_struct_ops programs,
reject execution when NULL is passed for non-nullable params.
For programs with non-nullable params verifier assumes that
such params are never NULL and thus might optimize out NULL checks.
