kunit: testing kunit: Bug fix in test_run_timeout function

Assert in test_run_timeout was not updated with the build_dir argument
and caused the following error:
AssertionError: Expected call: run_kernel(timeout=3453)
Actual call: run_kernel(build_dir=None, timeout=3453)

Needed to update kunit_tool_test to reflect this fix
