radv: fix dual source blending
Add the index to the location when assigning driver locations for
output variables.
Otherwise two fragment shader outputs declared as:
layout (location = 0, index = 0) out vec4 output1;
layout (location = 0, index = 1) out vec4 output2;
will end up aliasing one another.
Note that this patch will make the second output variable in the above
example alias a possible third output variable with location = 1 and
index = 0. But this shouldn't be a problem in practice since only one
color attachment is supported when dual-source blending is used.
