Tmpfiles: create and delete entries once in the boot runlevel.

Initially, we were creating tmpfiles entries in the sysinit runlevel and
again in the boot runlevel. Systemd runs the --create and --remove
options in one service called systemd-tmpfiles-setup after the local
file systems are mounted. Now we have a service called tmpfiles.setup
which emulates this.

This also closes the bug mentioned below, since we were originally
writing to files that were on read-only file systems and that were not
available.
