core/socket: fix reversed symlink direction in error message

After the update to 260-rc1 in Fedora Rawhide, we get a lot of messages like
this:
  systemd[1]: systemd-resolved-monitor.socket:
  Failed to create symlink /run/systemd/resolve/io.systemd.Resolve.Monitor →
  /run/varlink/registry/io.systemd.Resolve.Monitor, ignoring: Permission denied

The actual issue will need to be fixed too, but let's fix the message first.
While at it, let's rename the variables to be meaningful.
