I have uploaded systemd with this patch from upstream:
https://github.com/systemd/systemd/commit/75890d949f92c412c0936b8536b2e0dc8f7dfb40

This will allow us to build the stubble kernel images without an .osrel
section, and will then stop the systemd tools from thinking these are
"UKIs" in systemd's view. Separate from this test failure, this change
is something that upstream systemd requested a while back, so it's a
win-win.

I will propose the necessary stubble change too.
