This would fail when /var/lib already existed. I fixed it by using
mkdir-p in a7199b7d994433eaabb989690887b921d053d761.

Yesterday was my first time using the system tests:
https://www.gnu.org/software/guix/manual/html_node/Running-the-Test-Suite.html#Running-the-Test-Suite

I assume they would have caught this, but I'm not sure. They definitely
would have caught my breakage of GRUB when I updated QEMU recently ;)
