When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang issues a warning, because test_name is passed into asprintf(3), which then changes it.
Fix this by simply removing the const qualifier. This is a local automatic variable in a very short function, so there is not much need to use the compiler to enforce const-ness at this scope.
