GSdx-hw: use CanUseSwSpriteRender in OI_JakGames. (#3463) 

In GSRendererHW, reuse the method CanUseSwSpriteRender for OI_JakGames.

As in current master, 16x16 "flat" sprite draws are performed via CPU: those are palette rendering better emulated with the SwSpriteRender.

Jak games do also many 64x64 "flat" draws, but mostly for render to texture effects that are already correctly emulated in the TC, so those draws are not done via CPU (as on the contrary happens for DBZ BT games).
