i965: Bail on the BLT path if BlitFramebuffer requires sRGB conversion.
Modern OpenGL BlitFramebuffer require sRGB encode/decode when
GL_FRAMEBUFFER_SRGB is enabled. The blitter can't handle this,
so we need to bail. On Gen4-5, this means falling back to Meta,
which should handle it.
We allow sRGB <-> sRGB blits, as decode then encode ought to be a noop
(other than potential precision loss, which nobody wants anyway).
