selftests/bpf: Test bpf_skc_to_mptcp_sock
This patch extends the MPTCP test base, to test the new helper
bpf_skc_to_mptcp_sock().
Define struct mptcp_sock in bpf_tcp_helpers.h, use bpf_skc_to_mptcp_sock
to get the msk socket in progs/mptcp_sock.c and store the infos in
socket_storage_map.
Get the infos from socket_storage_map in prog_tests/mptcp.c. Add a new
function verify_msk() to verify the infos of MPTCP socket, and rename
verify_sk() to verify_tsk() to verify TCP socket only.
v2: Add CONFIG_MPTCP check for clearer error messages
v4:
- use ASSERT_* instead of CHECK_FAIL (Andrii)
- drop bpf_mptcp_helpers.h (Andrii)
v5:
- some 'ASSERT_*' were replaced in the next commit by mistake.
- Drop CONFIG_MPTCP (Martin)
- Use ASSERT_EQ (Andrii)
