[SYCL] Remove dependency of libspirv-nvptx64 for Driver LIT test (#20386)
We met some lit failure complaining
remangled-l64-signed_char.libspirv-nvptx64-nvidia-cuda.bc couldn't be
found when we ran clang lit tests without building libclc component. In
fact, we have put fake
remangled-l64-signed_char.libspirv-nvptx64-nvidia-cuda.bc files in
test/Driver/Inputs folder to remove the dependency but some tests didn't
use these fake files. This PR fix it.
