Subject: nixos/oxidized: Use symlinks for config files

The old `cp` suffers from a permission issue on the 2nd start of the
service. The files were copied from the read-only nix store. On the 2nd
start of the service the `cp` failed.
The new version force creates a symlink which does not suffer from this.
