validation: run CLI with correct argument order
validation: run CLI with correct argument order

The OCI Runtime Command Line Interface [1][1] specifies the order of the
arguments:

```
$ funC [global-options] <COMMAND> [command-specific-options] <command-specific-arguments>
```

runc [2][2] is flexible whether command-specific-options is before or
after command-specific-arguments. But crun [3][3] is not, making the
tests fail. Since the CLI spec only specifies one order, the validation
tests should respect that order.
