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.
