See https://github.com/siderolabs/image-factory/issues/43
Two fixes:
* pass path to the dtb, uboot and rpi-firmware explicitly
* include dtb, uboot and rpi-firmware into arm64 installer image when
generated via imager (regular arm64 installer was fine)
(The generation of SBC images was not broken for Talos itself, but only
when used via Image Factory).

Support full configuration for image generation, including image
outputs, support most features (where applicable) for all image output
types, unify image generation process.
