output: JSON: fix possible leak in error-handling.

The `realloc` extending the buffer containing the JSON to allow us to
insert a final new-line may fail.  Therefore, we need to assign the
return-value to a temporary variable or we will not able to free the
existing buffer on error.

Use the correct type for `buflen`.
