Thanks! This is probably overdue: while I still think we want to avoid
this being necessary for most uses, it definitely was a gap in
kunit_tool functionality.

I tested this and it worked fine, but did cause several of the
kunit_tool_tests to fail, largely due to there being changes to the
arguments of run_kernel(). Those should just require the associated
tests to be updated.
