[llvm] workflows/build-ci-container: Make sure to only test local containers (PR #120827)

[Tom Stellard via llvm-commits]

https://github.com/tstellar created https://github.com/llvm/llvm-project/pull/120827

The container test is run before we create the :latest tag, so we should not try testing this, otherwise it will pull the :latest tag from the github registry, and won't test the container we just built.
