Subject: rng-tools: Import recipe from meta-openembedded

Adding this recipe to oe-core will allow it to be used by qemu to
provide a way to generate additional entropy needed to fix hangs
with getrandom().

Additional kernel config options have already been added to the
default qemu kernel configs.
