Now fwupd is showing us dbx updates, it seems we get *both* a
"Restart & Update..." button *and* a "Download" button at the
same time. If we click Restart & Update without clicking Download
first, package updates aren't applied.
So, tweak this logic yet again so that it 'breaks the tie' in
the way we want (if both buttons are present, click the download
one, take download out of the tags, and go to the next loop
iteration). Hopefully this solves the problem without breaking
any other paths.
