[Qemu-block] [PULL 1/5] iotests: rewrite 192 to use _launch_qemu to fix LUKS support

[Eric Blake]

From: "Daniel P. Berrange" <address@hidden>

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
