scripts: test.py/bench.py: Added ifndef attribute for tests/benches

Browse Source 
As you might expect, this is the inverse of ifdef, and is useful for
supporting opt-out flags.

I don't think ifdef + ifndef is powerful enough to handle _all_
compile-time corner cases, but they at least provide convenient handling
for the most common flags. Worst case, tests/benches can always include
explicit #if/#ifdef/#ifndef statements in the code itself.
