bpf/selftests: Fix couldn't retrieve pinned program in xdp veth test

Browse Source 
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]

For the test case, the following can be found:

  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/
  xdp_redirect_map_0  xdp_redirect_map_1  xdp_redirect_map_2
