[HIP] Avoid append dup args in TranslateArgs after b37be0e

b37be0e started to TranslateArgs for SYCL too,
so we may endup getting dup args, eg:

/__w/llvm/llvm/build/bin/clang --driver-mode=g++  -Xsycl-target-backend=amdgcn-amd-amdhsa --offload-arch=gfx906 -fsycl-device-only -fsycl-targets=amd_gpu_gfx90a -S -Xclang -emit-llvm /__w/llvm/llvm/src/sycl/test/check_device_code/hip/matrix/matrix-hip-double-double-test.cpp -o -| FileCheck /__w/llvm/llvm/src/sycl/test/check_device_code/hip/matrix/matrix-hip-double-double-test.cpp
