pkg/wireguard: allow specifying iface named

Browse Source 
This commit makes it possible to specify the Kilo interface name. If the
specified interface exists, it will be used; if it does not exist, Kilo
will create it. If the interface already existed, then it will not be
deleted on shutdown; otherwise Kilo will destroy the interface.
