selftests/bpf: Check bpf_cubic_acked() is called via struct_ops
Test bpf_tcp_ca (in test_progs) checks multiple tcp_congestion_ops.
However, there isn't a test that verifies functions in the
tcp_congestion_ops is actually called. Add a check to verify that
bpf_cubic_acked is actually called during the test.
