Since more processes depend on good randomness, we need to
make sure that the kernel's PRNG is initialized as early as
possible.
For systems without a HWRNG, we will need to fall back to our
noisy loop and wait until we have enough randomness.
This patch also removes saving and restoring the seed. This
is no longer useful because the kernel's PRNG only takes any
input after it has successfully been seeded from other sources.
Hence adding this seed does not increase its randomness.

the script wait until crng is correct initialized before restore the
random seed and make some disc io to work around low entropy at boot
on some machines. Not really a fix but it should be better than reverting
CVE-2018-1108 fixes from kernel.
