Description of problem:
kernel源码包中tools/testing/selftests/bpf目录下Makefile在install阶段少拷贝文件，导致执行bpf.test_tcpbpf_user报错./tcp_server.py: No such file or directory

报错日志如下：
selftests: bpf: test_tcpbpf_user
sh: ./tcp_server.py: No such file or directory
FAILED: TCP server
not ok 1..10 selftests: bpf: test_tcpbpf_user [FAIL]

tools/testing/selftests/bpf目录Makefile相关内容===========缺少tcp_client.py和tcp_server.py文件的拷贝动作
# Order correspond to 'make run_tests' order
TEST_PROGS := test_kmod.sh \
        test_libbpf.sh \
        test_xdp_redirect.sh \
        test_xdp_meta.sh \
        test_offload.py \
        test_sock_addr.sh \
        test_tunnel.sh \
        test_lwt_seg6local.sh \
        test_lirc_mode2.sh \
        test_skb_cgroup_id.sh

How reproducible:
手动必现

Steps to Reproduce:

下载当前内核对应的kernel源码包
rpm -ivh xxx.src.rpm  默认安装到/root下
yum-builddep -y rpmbuild/SPECS/kernel.spec   自动安装前置依赖包，需要yum-utils
rpmbuild -bp ./rpmbuild/SPECS/kernel.spec   
cd rpmbuild/BUILD/kernel-xxx/linux-xxx/  

接下来就可以编译测试了
cd  ./tools/testing/selftests/bpf/
make
cd ..
./kselftest_install.sh $dir=======拷贝执行文件到指定目录

在指定目录下执行测试用例
./test_tcpbpf_user

Actual results:
用例执行失败

Expected results:
用例执行通过
