[4/5] ddraw: take alpha from diffuse color for D3DTBLEND_MODULATE

[Alexander Dorofeyev]

This and 5/5 patch are needed to make the TEXTUREMAPBLEND tests (patch 3/5)
pass, and also to fix the last remaining issue with Aliens vs Predator 1 HUD and
menu text rendering (http://bugs.winehq.org/show_bug.cgi?id=10797) as well as
some other alpha effects in game, that are done by setting alpha component of
diffuse color.
