Subject: [PATCH] tools/testing/selftests/bpf/test_xdp_veth.sh: fix Couldn't retrieve pinned program

Before change:
 selftests: bpf: test_xdp_veth.sh
 Couldn't retrieve pinned program '/sys/fs/bpf/test_xdp_veth/progs/redirect_map_0': No such file or directory
 selftests: xdp_veth [SKIP]
ok 20 selftests: bpf: test_xdp_veth.sh # SKIP

After change:
PING 10.1.1.33 (10.1.1.33) 56(84) bytes of data.
64 bytes from 10.1.1.33: icmp_seq=1 ttl=64 time=0.320 ms--- 10.1.1.33 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.320/0.320/0.320/0.000 ms
selftests: xdp_veth [PASS]

In test:
ls /sys/fs/bpf/test_xdp_veth/progs/redirect_map_0
ls: cannot access '/sys/fs/bpf/test_xdp_veth/progs/redirect_map_0': No such file or directory
ls /sys/fs/bpf/test_xdp_veth/progs/
