i965: Use swizzles to force R, G, and B to 0.0 for ALPHA textures.
Similar to the previous commit, we may be using a texture with actual RGBA
storage for the GL_ALPHA format, so force the color values to 0.0.
This commit fixes the following piglit (sub) tests:
EXT_texture_snorm/fbo-blending-formats
GL_ALPHA16_SNORM
GL_ALPHA8_SNORM
GL_ALPHA_SNORM
Note: Haswell bypasses this swizzle code, so may require an independent fix
for this bug.
