support/testing: add docker / docker-compose tests

Build for x86-64 as public containers in general are only available for x86-64. Docker needs a number of kernel options enabled, so use a custom kernel config based on the qemu one. Docker needs entropy at startup, so enable the virtio-rng-pci device to expose entropy to the guest. The default RAM amount (128M) is not enough to run docker / docker-compose, so bump to 512MB.
