bpf: selftest: Adapt sock_fields test to use skel and global variables
skel is used.
Global variables are used to store the result from bpf prog.
addr_map, sock_result_map, and tcp_sock_result_map are gone.
Instead, global variables listen_tp, srv_sa6, cli_tp,, srv_tp,
listen_sk, srv_sk, and cli_sk are added.
Because of that, bpf_addr_array_idx and bpf_result_array_idx are also
no longer needed.
CHECK() macro from test_progs.h is reused and bail as soon as
a CHECK failure.
shutdown() is used to ensure the previous data-ack is received.
The bytes_acked, bytes_received, and the pkt_out_cnt checks are
using "<" to accommodate the final ack may not have been received/sent.
It is enough since it is not the focus of this test.
The sk local storage is all initialized to 0xeB9F now, so the
check_sk_pkt_out_cnt() always checks with the 0xeB9F base. It is to
keep things simple.
The next patch will reuse helpers from network_helpers.h to simplify
