[SYCL] Make sure lit tests use absolute path for SPIRV tools (#6854)

llvm-lit has a list of tools where it uses the absolute path to make
sure it's using the in-tree version. llvm-spirv and spirv-to-ir-wrapper
weren't in the list so it used just the binary name, making it possible
for another one on the path to be picked up
