Fixed SDL_ISPIXELFORMAT_ALPHA to check pixel orders that match pixel type.
Otherwise, SDL_PIXELFORMAT_BGR24 is reported as having alpha, because
its SDL_ARRAYORDER_BGR pixel order uses the same integer value as
SDL_PACKEDORDER_RGBA, since we weren't checking the pixel type to
differentiate.
Fixes Bugzilla #2977.
