Dead hero's map coordinates are set to <0,0> part way through bones
creation, then were being used to record grave location for overview
feedback with "final resting place for <dead hero>" if/when another
character got those bones and found the grave (actually, spotted the
location where first hero died regardless of whether a grave gets
placed there). Record dead hero's pre-<0,0> coordinates as intended.
Not previously noticed because in wizard mode the final resting place
becomes part of overview info as soon as bones are loaded rather than
waiting for the death location to be reached.
