Achilleas Koutsou 83fcc8a0b1 test: compare full arg_list in chroot context test
- Add an extra call to `/bin/false` and explicitly set the `check`
  argument for both `run()` calls.
- Compare full call_args_list.  This checks that all the options are as
  expected, that the `check` argument is set properly, and that the full
  order of all the calls is as expected, including the chroot path.
