wt_status_print() is the only caller of wt_status_get_detached_from().
The latter performs most of the analysis of a detached HEAD, including
finding state->detached_from; the caller checks whether the detached
HEAD is still at state->detached_from or has moved away.
Move that last bit of analysis to wt_status_get_detached_from(), too,
and store the boolean result in state->detached_at.
