perf tests: Consolidate test__arch_unwind_sample declaration

There's no reason for making the test__arch_unwind_sample declaration per
arch. Currently that's done 2 different ways either with a declaration in
arch-tests.h or with an arch define. Unify all this with an unconditional
declaration in tests.h.
