[PATCH v2 1/1] qemu-iotests: Use ppc64 qemu_arch on ppc64le host

[Lukáš Doktor <ldoktor@xxxxxxxxxx>]

The qemu target does not always correspond to the host machine type. For
example ppc64le machine target is ppc64. Let's introduce "qemu_arch"
variable to store the matching qemu architecture related to the current
architecture and use it when auto-detecting the default qemu binary.
