Subject: [PATCH] Install and use sysusers.d/tmpfiles.d config files

sysusers.d/tmpfiles.d config files allow a package to use declarative
configuration instead of manually written maintainer scripts.
This also allows image-based systems to be created with /usr/ only, and
also allows for factory resetting a system and recreating /etc/ on boot.
