bpf: tcp: Add bpf_cubic example
This patch adds a bpf_cubic example. Some highlights:
1. CONFIG_HZ .kconfig map is used.
2. In bictcp_update(), calculation is changed to use usec
resolution (i.e. USEC_PER_JIFFY) instead of using jiffies.
Thus, usecs_to_jiffies() is not used in the bpf_cubic.c.
3. In bitctcp_update() [under tcp_friendliness], the original
"while (ca->ack_cnt > delta)" loop is changed to the equivalent
"ca->ack_cnt / delta" operation.
