The LUKS driver requires extra args to QEMU to setup passwords.
The _launch_qemu function takes care of this, so convert the
test to use this function and use correct -drive syntax

Can this test use QMP instead of HMP? But that's an independent question.

As far as I am concerned, there is nothing wrong with having HMP tests.
HMP commands already call QMP internally (except for the generic QMP
code path below the command handlers), so using HMP actually increases
the test coverage in most cases. We should try to have a good mix of
test cases using QMP and test cases using HMP.
