[WIP] Introduce prepare-integration make target

[jimmykarily]

to prepare the VM filesystem for the tests.
This target is suppused to be run like so:

make prepare-integration integration

but currently the filesystem it creates is not bootable for some reason.

@Foxboron looking at the code it seems that there is some way to run the integration test but it's relying on things outside git. I tried to fill in the missing parts by wrapping the make_image.sh script in a docker command that would make it possible to run it locally.

I remember you mentioned u-root being used in go-uefi so I wonder if I should ditch this and try to use u-root to build an initramfs that has sbctl in it. What do you think? I'm also fine dropping this completely until you find time to work on it yourself. I only mean to help, no pressure :).

Thanks for taking stabs at the project :)

I think moving the current tests from the old vmtest library to the u-root library like I've done in go-uefi would make all of this simpler.

Mind me giving it a try?
