Subject: [PATCH] random-seed: add missing header for GRND_NONBLOCK

GRND_NONBLOCK has been introduced with the 3.17 kernel version [1]
while adding getrandom(2) system call.

The header missing_random.h is needed for random-seed.c when building
with old toolchain, such Sourcery CodeBench ARM 2014.05.
