Subject: [PATCH 2/5] libbpf: add missing typedef

Sync tools/include/linux/types.h with the UAPI one to fix this build error:

make -C samples/bpf/../../tools/lib/bpf/ RM='rm -rf' LDFLAGS= srctree=samples/bpf/../../ O=
  HOSTCC  samples/bpf/sock_example
In file included from samples/bpf/sock_example.c:27:
/usr/include/linux/ip.h:102:2: error: unknown type name ‘__sum16’
  102 |  __sum16 check;
      |  ^~~~~~~
make[2]: *** [scripts/Makefile.host:92: samples/bpf/sock_example] Error 1
make[1]: *** [Makefile:1763: samples/bpf/] Error 2
