st/mesa: redefine mapping from VARYING_SLOT_TEXi/PNTC/VARi to TGSI GENERIC[i]
Generic varyings in TGSI were based on the value of VARYING_SLOT_TEX0, so VAR0
was always GENERIC[22] (with tessellation patches). Some drivers might not
be able to cope with that.
This commit defines a proper mapping, so that PNTC is GENERIC[8] and VAR0 is
GENERIC[9].
