Benchtests: Remove simple_strcspn/strpbrk/strsep

Remove simple_strcspn/strpbrk/strsep which are significantly slower than the
generic implementations.  Also remove oldstrsep and oldstrtok since they are
practically identical to the generic implementation.  Adjust iteration count
to reduce benchmark time.
