kunit: tool: fix typecheck errors about loading qemu configs
Currently, we have these errors: $ mypy ./tools/testing/kunit/*.py tools/testing/kunit/kunit_kernel.py:213: error: Item "_Loader" of "Optional[_Loader]" has no attribute "exec_module" tools/testing/kunit/kunit_kernel.py:213: error: Item "None" of "Optional[_Loader]" has no attribute "exec_module" tools/testing/kunit/kunit_kernel.py:214: error: Module has no attribute "QEMU_ARCH" tools/testing/kunit/kunit_kernel.py:215: error: Module has no attribute "QEMU_ARCH" exec_module =========== pytype currently reports no errors, but that's because there's a comment disabling it on 213. This is due to https://github.com/python/typeshed/pull/2626. The fix is to assert the loaded module implements the ABC (abstract base class) we want which has exec_module support. QEMU_ARCH ========= pytype is fine with this, but mypy is not: https://github.com/python/mypy/issues/5059 Add a check that the loaded module does indeed have QEMU_ARCH. Note: this is not enough to appease mypy, so we also add a comment to squash the warning.
