selftests/bpf: Add parallel support for classid
Include the current pid in the classid cgroup path. This way, different
testers relying on classid-based configurations will have distinct classid
cgroup directories, enabling them to run concurrently. Additionally, we
leverage the current pid as the classid, ensuring unique identification.

bpf, selftests: Add test case for mixed cgroup v1/v2
Minimal selftest which implements a small BPF policy program to the
connect(2) hook which rejects TCP connection requests to port 60123
with EPERM. This is being attached to a non-root cgroup v2 path. The
test asserts that this works under cgroup v2-only and under a mixed
cgroup v1/v2 environment where net_classid is set in the former case.
Before fix:
# ./test_progs -t cgroup_v1v2
test_cgroup_v1v2:PASS:server_fd 0 nsec
test_cgroup_v1v2:PASS:client_fd 0 nsec
test_cgroup_v1v2:PASS:cgroup_fd 0 nsec
test_cgroup_v1v2:PASS:server_fd 0 nsec
run_test:PASS:skel_open 0 nsec
run_test:PASS:prog_attach 0 nsec
test_cgroup_v1v2:PASS:cgroup-v2-only 0 nsec
run_test:PASS:skel_open 0 nsec
run_test:PASS:prog_attach 0 nsec
run_test:PASS:join_classid 0 nsec
(network_helpers.c:219: errno: None) Unexpected success to connect to server
test_cgroup_v1v2:FAIL:cgroup-v1v2 unexpected error: -1 (errno 0)
#27 cgroup_v1v2:FAIL
Summary: 0/0 PASSED, 0 SKIPPED, 1 FAILED
After fix:
# ./test_progs -t cgroup_v1v2
#27 cgroup_v1v2:OK
Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED
