bpf_object__find_program_by_title’ is deprecated: libbpf v0.7+:
use bpf_object__find_program_by_name() instead
See: https://github.com/libbpf/libbpf/issues/297
libbpf#297 Deprecate bpf_program__title() in favor of
bpf_program__section_name(). “Title” term is confusing and
unconventional, it’s SEC() in code and “section name” everywhere else.

Minimal example to show that the close() operation on a bpf_link can hang
indefinitely if the kernel is loaded (for example by traffic on an
interface with an XDP program loaded).
