[PATCH 22/27] [AARCH64] ILP32: support stat syscall family

[Yury Norov <ynorov@caviumnetworks.com>]

From: Yury Norov <yury.norov@gmail.com>

stat and statfs structures has their layouts identical to lp64
after changing off_t, ino_t etc sizes to 64-bit. It means we can
pass it to kernel same way as lp64 does.
