They were removed during one of the syncs because Linux repo's tools/ versions of UAPI headers were removed (as they were not needed for perf anymore). This is no right for libbpf, so add them back. And moving forward, we'll sync them from Linux repo original UAPIs. Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
