fdo#81384: writerfilter: turn the horrible btLr cell text dir hack

... by 5 degrees to starboard, which lets the row in the bugdoc appear,
altough the height is a bit insufficient still.  Why that works, is a
nautic mystery to me, i'd say this whole btLr emulation nonsense needs
to be keel-hauled, but after this patch i'll need some rum, arrrr...
