So, unfortunately oomd uses "io.system." rather than "io.systemd." as prefix for its sockets. This is a mistake, and doesn't match the Varlink interface naming or anything else in oomd. hence, let's fix that. Given that this is an internal protocol between PID1 and oomd let's simply change this without retaining compat.
