Fix single-record reads to use restore_command if available in pg_rewind

readOneRecord() is used now when looking for a checkpoint record to
check if the target server is an ancestor of the source across multiple
timelines, and using a restore_command if available improves the
stability of the operation.  This part was missed in a7e8ece.
