[AD] 16 bit C version of stretch_blit() fixed

[Sven Sandberg <ssven.geo@xxxxxxxxxx>]

Sorry for cross-posting; I accidentally sent this to [AL] first.

Here is a fix to the bug that I mentioned some weeks ago that caused
exalpha to look wrong. It was caused by a typo in the 16 bit generic C
stretch_blit() code.
