lima: lower fmod in ppir and gpir

Since commit 4f3c82c72c5 fmod is no longer being lowered in nir, and
ends up crashing lima programs with "unsupported nir_op: fmod" in both
ppir and gpir.
There seems to be no mod operation in hardware in utgard and there is an
optimization in nir to lower fmod to instructions that lima already
implements, so let's use that.
