Subject: [PATCH 08/13] tools: Synchronize tools/include/uapi/linux/bpf.h

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Commit 747ea55e4f78 ("bpf: fix bpf_skb_in_cgroup helper naming") renames
BPF_FUNC_skb_in_cgroup to bpf_skb_under_cgroup, triggering this warning
while building perf:

  Warning: tools/include/uapi/linux/bpf.h differs from kernel

Update the copy to ack that, no changes needed, as
BPF_FUNC_skb_in_cgroup isn't used so far.
