tools headers: Fixup tools/include/uapi/linux/bpf.h copy of kernel ABI header 

In 04df41e343 ("bpf: update tools/include/uapi/linux/bpf.h") the files
added in 40304b2a15 ("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/.
