random: If we have arch_get_random_seed*(), try it before blocking
If we have arch_get_random_seed*(), try to use it for emergency refill
of the entropy pool before giving up and blocking on /dev/random. It
may or may not work in the moment, but if it does work, it will give
the user better service than blocking will.
