ZigLLVMTargetMachineEmitToFile: put sanitizers in registerOptimizerLastEPCallback

matching the default of clang's behavior. I originally put them in
registerOptimizerEarlyEPCallback because I thought clang was doing that,
but I see now it is behind the flag `--sanitizer-early-opt-ep` which is
disabled by default.
