[bazel] Fix LLVM plugin tests under Analysis.

Those tests were broken on bazel as a side effect of 8830e38.

This commit is tested with this command on Linux:

    bazelisk test \
        @llvm-project//llvm/unittests:analysis_tests \
        @llvm-project//llvm/unittests:plugin_inline_advisor_analysis_test \
        @llvm-project//llvm/unittests:plugin_inline_order_analysis_test
