Use --sysroot for device libraries in sycl-device-lib-nvptx.cpp (#15282)

Adds the `--sysroot` option to `clang` invocations in `clang/test/Driver/sycl-device-lib-nvptx.cpp` , pointing the compiler to `clang/test/Driver/Inputs/SYCL`, so that it uses the mock files for libraries, making the test pass even when DPC++ is not configured with `--cuda` (similarly to how it's done for other SYCL driver lit tests).
