Tests: Silence warnings about unused functions from tuktest.h.
Warnings about unused tuktest_run_test conveniently tell which test programs haven't been converted to tuktest.h yet but I silenced that warning too for now anyway. It is fine to use __attribute__((__unused__)) even when the function is actually used because the attribute only means that the function might be unused.
