selftests/bpf: Turn on libbpf 1.0 mode and fix all IS_ERR checks Turn ony libbpf 1.0 mode. Fix all the explicit IS_ERR checks that now will be broken because libbpf returns NULL on error (and sets errno). Fix ASSERT_OK_PTR and ASSERT_ERR_PTR to work for both old mode and new modes and use them throughout selftests. This is trivial to do by using libbpf_get_error() API that all libbpf users are supposed to use, instead of IS_ERR checks. A bunch of checks also did explicit -1 comparison for various fd-returning APIs. Such checks are replaced with >= 0 or < 0 cases. There were also few misuses of bpf_object__find_map_by_name() in test_maps. Those are fixed in this patch as well.

selftests/bpf: Test updating flow_dissector link with same program This case, while not particularly useful, is worth covering because we expect the operation to succeed as opposed when re-attaching the same program directly with PROG_ATTACH. While at it, update the tests summary that fell out of sync when tests extended to cover links.

selftests/bpf: Restore the netns after flow dissector reattach test flow_dissector_reattach test changes the netns we run in but does not restore it to the one we started in when finished.
