test_hush_if_test.py executes commands that require large values of CONFIG_SYS_MAXARGS. Detect cases where the configured value is too low and skip those tests. Ideally, this would be implemented inside console.run_command(). However, the command passed to that function is already a completely formed string, and determining its argument count usage would require splitting commands at ;, handling quoting to deal with arguments containing spaces, etc. Even passing the command as a list wouldn't solve all these issues, since we'd still need to split commands on ; and deal with cases like "if test ..." which consumes 0 of the argument count.
