[CI] Temporarily disable tests requiring spirv-tools in CI (#16743)

#16724 installed `spirv-tools` on
Linux docker containers and now some llvm-spirv tests are failing due to
this (example:
https://github.com/intel/llvm/actions/runs/12915358763/job/36017038536).
In this PR, we disable detection of `spirv-tools` LIT feature
temporarily in CI to fix post-commit.
