There is an existing "bpf_tcp_ca/unsupp_cong_op" test to ensure the unsupported tcp-cc "get_info" struct_ops prog cannot be loaded. This patch adds a new test in the bpf_testmod such that the unsupported ops test does not depend on other kernel subsystem where its supporting ops may be changed in the future.
