[UpdateCCTestChecks] Fix new test from 9eaf0d120d32

`clang/test/utils/update_cc_test_checks/check-globals.test` from
9eaf0d120d32 broke at:

* <https://lab.llvm.org/buildbot/#/builders/110/builds/4415>
* <https://lab.llvm.org/buildbot/#/builders/5/builds/9076>

The problem is non-deterministic test order because the
`.lit_test_times.txt` from one run of a sample test suite affects the
other.
