Subject: [RFC PATCH 1/2] kunit: tool: Move qemu architecture dependency checks
 into a function

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.
