Make timespec pointers, pointers to const in checklist function. As a
consequence, make list parameter in checklist function pointer to const
as well. Const-correctness increases readability.

Improvement was found by running cppcheck tool on the patched file as
follows:
```
cppcheck --enable=all \
	tools/testing/selftests/timers/threadtest.c \
	--suppress=missingIncludeSystem \
	--suppress=unusedFunction
```
