bpf: Sync kernel ABI header with tooling header

Update tools/include/uapi/linux/bpf.h to bring it in sync with
include/uapi/linux/bpf.h.  The listed commits forgot to update it.

Fixes: 02dd3291b2f0 ("bpf: finally expose xdp_rxq_info to XDP bpf-programs")
Fixes: f19397a5c656 ("bpf: Add access to snd_cwnd and others in sock_ops")
Fixes: 06ef0ccb5a36 ("bpf/cgroup: fix a verification error for a CGROUP_DEVICE type prog")
