b672316bc7 use const for memory_corruption_check_small 
This currently causes a warning (treated as an error) on Android where
malloc_usable_size uses a const pointer.

d757835d90 increase size for eight_byte_overflow_large test 
This was not working as expected due to CONFIG_EXTENDED_SIZE_CLASSES
resulting in 128k being a slab allocation size class. The addition of
padding for the canary pushes it into the next size class, resulting in
this writing over size class rounding padding rather than this actually
being an overflow as intended.
