bpf: selftests: Bpf_cubic and bpf_dctcp calling kernel functions
This patch removes the bpf implementation of tcp_slow_start()
and tcp_cong_avoid_ai(). Instead, it directly uses the kernel
implementation.
It also replaces the bpf_cubic_undo_cwnd implementation by directly
calling tcp_reno_undo_cwnd(). bpf_dctcp also directly calls
tcp_reno_cong_avoid() instead.
