glsl: Don't use MOD_TO_FRACT lowering on GLSL 1.30's % operator.
MOD_TO_FRACT was designed to lower the GLSL 1.20 mod() function, which
operates on floating point values. However, we also use ir_binop_mod
for GLSL 1.30's % operator, which operates on integers.
For now, make MOD_TO_FRACT only apply to floating-point mod operations.
In the future, we may want to add a lowering pass for integer-based mod.
