selftests/bpf: Test if shadow types work correctly. Change the values of fields, including scalar types and function pointers, and check if the struct_ops map works as expected. The test changes the field "test_2" of "testmod_1" from the pointer to test_2() to pointer to test_3() and the field "data" to 13. The function test_2() and test_3() both compute a new value for "test_2_result", but in different way. By checking the value of "test_2_result", it ensures the struct_ops map works as expected with changes through shadow types.

selftests/bpf: test case for register_bpf_struct_ops(). Create a new struct_ops type called bpf_testmod_ops within the bpf_testmod module. When a struct_ops object is registered, the bpf_testmod module will invoke test_2 from the module.
