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.
