libbpf: Add uprobe multi link support to bpf_program__attach_usdt
Adding support for usdt_manager_attach_usdt to use uprobe_multi
link to attach to usdt probes.
The uprobe_multi support is detected before the usdt program is
loaded and its expected_attach_type is set accordingly.
If uprobe_multi support is detected the usdt_manager_attach_usdt
gathers uprobes info and calls bpf_program__attach_uprobe to
create all needed uprobes.
If uprobe_multi support is not detected the old behaviour stays.
Also adding usdt.s program section for sleepable usdt probes.
