Before booting the guest images, the distro test cases need to modify the
guest images, using virt-edit and guestfish, to boot in the way we need.
At present this gets repeated on every test run, even though it's not
really doing anything we want to test for.
In addition many of the images have the same preparation steps leading to
a lot of duplicated stages in the tests. A number of additional images can
be prepared using common steps, even if the ones used now have small
differences.
Therefore move the preparation of most of the guest images to the asset
build phase, where they can be done a single time for multiple test runs,
using a common preparation script. We can even avoid making a copy of the
disk image for booting, by using qemu's -snapshot option.
A few of the distros (openSUSE and older Ubuntu) do need different steps.
For now we don't chage how they are run, they could possibly be handled
more like this in future.

Rather than directly download distro images from the test scripts, handle
all the downloads during the test asset build, then just clone them for
the tests themselves. This avoids repeated downloads which can be very
slow when debugging failing tests.

[sbrivio: Add OPENSUSE_IMGS to DOWNLOAD_ASSETS in Makefile, and note
that xzcat doesn't take a -O option in test/distro/opensuse]

Apparently qemu's ARM virt machine needs to be explicitly given a firmware
image, rather than just supplying a sane default. Unfortunately the EDK2
firmware image we need isn't in the same place on all host distros.
Currently the test scripts hardcode the Debian location, meaning it will
break on hosts that have it somewhere else. This patch searches multiple
locations for the firmware, and creates a local link during the asset build
phase, which the tests can then use.
For now it only searches the locations used by Debian and Fedora, but
that's a small improvement in robustness already, and can be later improved
further if we need to.

Move the download of mbuto and using it to create a sample initramfs to
the asset build makefile, rather than embedding it in the test scripts
themselves.
The two_guests tests used to use two separate copies of the mbuto
image. As an initramfs the mbuto image is strictly readonly though,
so that's not necessary. So, also use the same image for both guests.

A number of passt/pasta testcases have initial steps which are just about
building images or other assets we need for the test proper. Repeating
these for each test run can be quite costly.
This patch makes a start on moving this sort of test asset building to
a separate phase before running the tests proper. For now just add a
Makefile to handle the asset building (although it doesn't build
anything yet), and make the path where we'll be building the assets
available to the tests.
