Subject: bpf, test_offload.py: Skip base maps without names
Patch-mainline: v5.19-rc1
Git-commit: 891663ace74c23321a40f4bae13e45a1803d5e20
References: jsc#PED-1377

The test fails:

  # ./test_offload.py
  [...]
  Test bpftool bound info reporting (own ns)...
  FAIL: 3 BPF maps loaded, expected 2
    File "/root/bpf-next/tools/testing/selftests/bpf/./test_offload.py", line 1177, in <module>
      check_dev_info(False, "")
    File "/root/bpf-next/tools/testing/selftests/bpf/./test_offload.py", line 645, in check_dev_info
      maps = bpftool_map_list(expected=2, ns=ns)
    File "/root/bpf-next/tools/testing/selftests/bpf/./test_offload.py", line 190, in bpftool_map_list
      fail(True, "%d BPF maps loaded, expected %d" %
    File "/root/bpf-next/tools/testing/selftests/bpf/./test_offload.py", line 86, in fail
      tb = "".join(traceback.extract_stack().format())

Some base maps do not have names and they cannot be added due to compatibility
with older kernels, see [0]. So, just skip the unnamed maps.
