bpf: Add cookie to perf_event bpf_link_info records
At the moment we don't store cookie for perf_event probes, while we do that for the rest of the probes. Adding cookie fields to struct bpf_link_info perf event probe records: perf_event.uprobe perf_event.kprobe perf_event.tracepoint perf_event.perf_event And the code to store that in bpf_link_info struct.
