bpf: Add cookie to perf_event bpf_link_info records
[ Upstream commit d5c16492c66fbfca85f36e42363d32212df5927b ]
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.
