Wei Fu a8fc3a0172 pkg/oci: resolve rootfs symlinks for user lookup
Some rootfs may use symlinks for /etc/passwd and /etc/group. For example,
NixOS uses absolute symlinks to files in /nix/store. os.Root is not used
because it rejects absolute symlinks.

The previous code only handled a symlink on the final path. Add a helper to
resolve symlinks in every path component with fs.ReadLinkFS. Absolute symlinks
are resolved from the rootfs, and the final path is still opened with fs.FS.

When tracing a path through symbolic links, the maximum number of links that
can be followed is [40][1].
