There really is no need to source a defined variable from a linux header. The OOM-rank ranges from -1000 to 1000, so we can safely hardcode -1000, which is a sane thing to do given slock is suid and we don't want to play around too much here anyway. On another notice, let's not forget that this still is a shitty heuristic. The OOM-killer still can kill us (thus I also changed the wording in the error-message. We do not disable the OOM-killer, we're just hiding.
