Adding debugging steps here for posterity.

vgchange -a y didn't work, complaining that a tool called thin_check wasn't available. This tool comes with thin-provisioning-tools.
I then installed thin-provisioning-tools and rebooted one more time. Now docker runs fine.
What's left to check here is if perhaps thin-provisioning-tools should be a strong or weak dependency of docker.io, like a Recommends or Suggests.
