This modification tries to solve issue #89 (closed): ASSERT ( r94 ls) CURIOSITY(ma->start + ma->os_data.alignment == base) at os.c:3549 Fix it by

1. only check module overlap if it is not vdso segment in find_executable_vm_areas.
2. add base == vsyscall_page_start in mmap_check_for_module_overlap
3. add note in find_executable_vm_areas, mmap_check_for_module_overlap, and process_mmap for possible issues to be solved.
