LOG: Add spirv backend registration guard to syncscope test (#215634)

This PR is just a hotfix for a test that assumed the spirv backend was
registered, introduced here:
https://github.com/llvm/llvm-project/pull/214592
Now we add a guard, so the test will be unsupported and not raise errors
on machines that don't have that backend registered.
Also improves a check pattern that could mismatch unintentionally.

Removed:
