Use temporary file for prng_seed

I wonder if this is a race condition in prng_seed creation/reading. Please give
this patch a try and see if it helps.

You might also want to try some stress-tests on ssh-rand-helper. E.g. something
like this:

for x in 0 1 2 3 4 5 6 7 8 9; do 
for y in 0 1 2 3 4; do 
sh -c "ssh-rand-helper -vvv > out.$x.$y 2>&1 || echo $x.$y failed" &
done ; done

This will run 50 concurrent ssh-rand-helpers, and should report on failures.
