Currently the RISC-V qemu architecture config has some code to check for the presence of the BIOS files before loading, printing a message and quitting if it's not present.
However, this prevents us from loading the architecture file even just to inspect it if the dependencies are not present. Instead, have kunit.py look for a check_dependencies function, and call it if present only when the architecture config is being used.
This is necessary for future changes which enumerate or automatically select an architecture.
