Make -T HANDLE and -B HANDLE always set last stat type

-T and -B on handles always set PL_laststatval (which indicates the
success of the previous stat).  But they don’t set the last stat type
(PL_laststype) for closed filehandles.  Those two should always go
together.  stat and -r, -w etc., always set PL_laststype for a closed
or missing filehandle.
