Only oidentd.socket and miredo.service were copied instead of being
units that exist in the system and they don't need to do anything
else than fix the issue I have with the stock units.
* oidentd.socket is IPv6-only on my systems unless is BindIPv6Only=both.
because of net.ipv6.bindv6only=1
* miredo.service is here because it starts before there is network
connection (network-online.target) and there is never network
connection with laptops before they are connected to WLAN even if
NetworkManager might be up seeking/connecting to network.
