Check that autocreate flags of struct_ops map cause autoload of struct_ops corresponding programs: - when struct_ops program is referenced only from a map for which autocreate is set to false, that program should not be loaded; - when struct_ops program with autoload == false is set to be used from a map with autocreate == true using shadow var, that program should be loaded; - when struct_ops program is not referenced from any map object load should fail.
