This should fix a rare bug regarding treating an exclusive range as an inclusive range when the zero_end is page aligned.

The `zero_end` bound is exclusive, but we treat the `end_page` as inclusive. So when `zero_end` is page-aligned, we allocate one additional bss page. If this page was already mapped to some other segment, we remap it to a page with random content.

This is the same bug as #362.
