only disable aligned_alloc if malloc was replaced but it wasn't

it both malloc and aligned_alloc have been replaced but the internal
aligned_alloc still gets called, the replacement is a wrapper of some
sort. it's not clear if this usage should be officially supported, but
it's at least a plausibly interesting debugging usage, and easy to do.
it should not be relied upon unless it's documented as supported at
some later time.
