Bug#927414: how best to do this

[dann frazier <dannf@dannf.org>]

This script is currently shipped in the edk2 source package in Ubuntu,
where it is used to pre-gen VARS images w/ Microsoft's keys pre-baked.
I plan to merge this delta into Debian soon after buster releases.
However, that will still not make it available to end users who may
want to generate images with their own keys pre-baked. Adding a new
deb to the distro isn't free, so I'd be interested in knowing if
there's a significant number of people who have that need and would
use this package to fulfill it.

Now, assuming we do have the users, what would be the best way to package it?

To make it apt-installable, I think we'd end up needing a new binary
package. Since presumably it could be useful for users of any of the
existing binary packages, we wouldn't want to just e.g. ship it in
ovmf. We could make edk2 build that new package, but I personally
don't like the idea of bundling out of tree source that is not tightly
coupled. If we take the hit and create a new deb, I'd lean towards
also keeping it in its own source package, and replace edk2's
(soon-to-be) bundled version w/ a build-dep on the new binary.
