In 04df41e343db ("bpf: update tools/include/uapi/linux/bpf.h") the files
added in 40304b2a1567 ("bpf: BPF support for sock_ops") were added to
tools/include, but not in a verbatim way, missing the comments, which
ends up triggering this warning when build tools/perf/:

make: Entering directory '/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j4' parallel build
Warning: Kernel ABI header at 'tools/include/uapi/linux/bpf.h' differs from latest version at 'include/uapi/linux/bpf.h'

Make sure the the lines are equal, to fix the simple header copy
drift detector in tools/perf/.
