Andrii Nakryiko 74efbe5b91 scripts: update sync script to do if_xdp.h syncing
With xsk.{o,h} changes we started including Linux UAPI's if_xdp.h
header. We need to sync it along the other UAPI headers.

Also updated README to reflect this.

This is a mirror of bpf-next linux tree
(https://kernel.googlesource.com/pub/scm/linux/kernel/git/bpf/bpf-next)
bpf-next/tools/lib/bpf directory plus its supporting header files.
The following files will by sync'ed with bpf-next repo:
src/ <-> bpf-next/tools/lib/bpf/
include/uapi/linux/bpf_common.h <-> bpf-next/tools/include/uapi/linux/bpf_common.h
include/uapi/linux/bpf.h <-> bpf-next/tools/include/uapi/linux/bpf.h
include/uapi/linux/btf.h <-> bpf-next/tools/include/uapi/linux/btf.h
include/uapi/linux/if_link.h <-> bpf-next/tools/include/uapi/linux/if_link.h
include/uapi/linux/if_xdp.h <-> bpf-next/tools/include/uapi/linux/if_xdp.h
include/uapi/linux/netlink.h <-> bpf-next/tools/include/uapi/linux/netlink.h
include/tools/libc_compat.h <-> bpf-next/tools/include/tools/libc_compat.h
Other header files at this repo (include/linux/*.h) are reduced versions of
their counterpart files at bpf-next/tools/include/linux/*.h to make compilation
successful.
Build
=====
To build static library libbpf.a:
cd src
make
To build both static libbpf.a and shared libbpf.so libraries in directory
build/ and install them together with libbpf headers in a staging directory
root/:
cd src
mkdir build root
BUILD_SHARED=y OBJDIR=build DESTDIR=root make install
