ctest: Restore enforcement of RESOURCE_LOCK test property

Refactoring in commit 5ff0b4ed57 (cmCTestMultiProcessHandler:
Consolidate test readiness checks, 2023-10-20, v3.29.0-rc1~378^2~4)
accidentally broke `RESOURCE_LOCK`.  Fix it and replace the previous
test with one that would have caught this.

Fixes: #25843
