Install rngd packages in the minimal images

With newer kernels it takes far longer in early boot to get random
numbers (as >= 4.18 kernels ensure good quality entropy is availble
before starting  providing randomness).

Install rng-tools to integrate with hardware random number generators
while jitterentropy-rngd can provide randomness without.
