libbpf: Add support for kprobe session attach
Adding support to attach program in kprobe session mode
with bpf_program__attach_kprobe_multi_opts function.
Adding session bool to bpf_kprobe_multi_opts struct that allows
to load and attach the bpf program via kprobe session.
the attachment to create kprobe multi session.
Also adding new program loader section that allows:
SEC("kprobe.session/bpf_fentry_test*")
and loads/attaches kprobe program as kprobe session.
