Paul Holzinger 2a8c414488 Fix rootless cni dns without systemd stub resolver
When a host uses systemd-resolved but not the resolved stub resolver the
following symlinks are created: `/etc/resolv.conf` ->
`/run/systemd/resolve/stub-resolv.conf` -> `/run/systemd/resolve/resolv.conf`.
Because the code uses filepath.EvalSymlinks we put the new resolv.conf
to `/run/systemd/resolve/resolv.conf` but the `/run/systemd/resolve/stub-resolv.conf`
link does not exists in the mount ns.
To fix this we will walk the symlinks manually until we reach the first
one under `/run` and use this for the resolv.conf file destination.

This fixes a regression which was introduced in e73d482990.

Fixes #11222
