samples, bpf: Replace bpf_program__title() with bpf_program__section_…

…name() From commit 5210958 ("libbpf: Deprecate notion of BPF program "title" in favor of "section name""), the term title has been replaced with section name in libbpf. Since the bpf_program__title() has been deprecated, this commit switches this function to bpf_program__section_name(). Due to this commit, the compilation warning issue has also been resolved. Fixes: 5210958 ("libbpf: Deprecate notion of BPF program "title" in favor of "section name"") Signed-off-by: Daniel T.
