sysdeps/stat: Handle 64-bit ino_t types on 32-bit hosts
On a 32-bit platform with a 64-bit ino_t type (__INO_T_MATCHES_INO64_T defined) we want to update the stat struct to remove the padding as it isn't required. As we don't have the padding we also need to update the overflow checker to not access the undefined members.
