Split emulation from needing an external kernel

With the addition of riscv64 we have a case that is using
emulation, but actually having a fine bootloader.

Splitting up the detection allows to boot properly the kernel on the
image/disk and furthermore to run it without root (which otherwise
would be needed to mount and extract the guest kernel on the host).

uvtool: switch ip guessing to libvirt-python

This allows to drop plenty of complex code and dependencies
and at the same time is not affected by all the snap path-munging.

snap: use non-accounted name test-snapd-uvtool

There is a snap namespace that is not going into the statistics so that
automated self-tests are not polluting the numbers e.g. showing this as
a "hot app" on the store after a night of automated tests.

template (x86): add spice graphics backend

In addition to the classic VNC backend add a spice backend to allow
leveraging more benefits of the QXL driver in the guest.

That allows users to upgrade their uvtool guest to a full Desktop and
get some meaningful performance. If they later on add the qxl.ko from
linux-modules-extra they even will get KMS and more extra features.

This will use the same "local only" mechanism that VNC uses to avoid
opening up to the world too much.

fix arm template nvram path

The body of that element defines a path where the per-guest custom copy
should be stored.
That has two issues:
 1. multiple guests would clash
 2. the path could be not writable by default

Fortunately if just not specified at all libvirt will make sane
defaults.

kvm: add --host-passthrough option

This allows users of uvtool to easily change from the compatibility
focused default cpu type to host-passthrough which will expose as much
as possible to the guest.

Anything in between is too specific for uvtool and can be setup via
libvirt after creating the guest.

template-s390x: drop non supported cpu features

This does not cause any issues, but apic, pae and such are just not

these int he template becomes a problem, therefore remove them now.
