The flow_dissector test integrated in test_progs actually runs a wide matrix of tests over different packets types and bpf programs modes, but exposes only 3 main tests, preventing tests users from running specific subtests with a specific input only. Expose all subtests executed by flow_dissector by using test__start_subtest().
