The first segment may contain program header so that the first section
in the first segment may not align with the first segment. In that
case, even if the first section in the first segment is removed, we
may still want to preserve segment virtual address. In that case,
first_section is NULL. We reset the segment virtual address only if
the first section, which is alignd with the segment, is removed.
