Fix bazel query failure for oneAPI (#168)

This PR resolves a CI failure where bazelisk query "deps(//xla/...)"
failed during transitive dependency evaluation due to the
https://github.com/oneapi hermetic repository enforcing ONEAPI_VERSION
and OS via --repo_env

Another change in the sycl.BUILD fixes the syntax error
