resolved: create /etc/resolv.conf symlink at runtimev239-8
If the symlink doesn't exists, and we are being started, let's create it to provie name resolution. If it exists, do nothing. In particular, if it is a broken symlink, we cannot really know if the administator configured it to point to a location used by some service that hasn't started yet, so we don't touch it in that case either. https://bugzilla.redhat.com/show_bug.cgi?id=1313085
