i965: Disable dual source blending when shader doesn't support it on gen8+
Dual source blending behaviour is undefined when shader doesn't
have second color output, dismissing fragment in such situation
leads to a hang on gen8+ if depth test in enabled.
Since blending cannot be gracefully fixed in such case and the result
is undefined - blending is simply disabled.
v2 (Kenneth Graunke):
- Listen to BRW_NEW_FS_PROG_DATA in 3DSTATE_PS_BLEND
- Also whack BLEND_STATE[] to keep the two in sync, since we're not
sure exactly which copy of the redundant info the hardware will use.
