[PATCH v2 1/2] automation: Switch ppc64le tests to PowerNV machine type

[Shawn Anastasio <sanastasio@xxxxxxxxxxxxxxxxxxxxx>]

Run ppc64le tests with the PowerNV machine type (bare metal) instead of
the paravirtualized pseries machine. This requires a more modern version
of QEMU than is present in debian bullseye's repository, so update the
dockerfile to build QEMU from source.

Support for booting on pseries was broken by 74b725a64d80 ('xen/ppc:
Implement initial Radix MMU support') which resulted in CI failures. In
preparation for removing pseries support entirely, switch the CI
infrastructure to the PowerNV machine type.
