selftests/bpf: Use bpf_tracing_net.h in bpf_dctcp

Browse Source 
This patch uses bpf_tracing_net.h (i.e. vmlinux.h) in bpf_dctcp.
This will allow to retire the bpf_tcp_helpers.h and consolidate
tcp-cc tests to vmlinux.h.

It will have a dup on min/max macros with the bpf_cubic. It could
be further refactored in the future.
