The 32-bit process_types definition of dyld_all_image_infos winds up
with four extra bytes of tail padding when built into a 64-bit
crashpad_handler compared to a 32-bit one, and compared to the
structure’s native size. This prevents a 64-bit crashpad_handler from
being able to create a module snapshot of a 32-bit process for
dyld_all_image_infos versions 14 (since 10.9) and 15 (since 10.12).
Work around this by placing a zero-length “end” marker and using
offsetof(dyld_all_image_infos, end) in preference to
sizeof(dyld_all_image_infos).
