TestVolumeOwnership: compare GID, not group name

Browse Source 
The name of the GID 65534 differs across distros.
("nogroup" on Debian derivatives, "nobody" on Red Hat derivatives)

Fix the following test failure:
```
=== RUN   TestVolumeOwnership
    volume_copy_up_test.go:103: Create a sandbox
    main_test.go:667: Pull test image "ghcr.io/containerd/volume-ownership:2.1"
    volume_copy_up_test.go:108: Create a container with volume-ownership test image
    volume_copy_up_test.go:117: Start the container
    volume_copy_up_test.go:125: Check ownership of test directory inside container
    volume_copy_up_test.go:146: Check ownership of test directory on the host
    volume_copy_up_test.go:153:
