Add R! to systemd-tmpfiles script for all /tmp dirs

Browse Source 
We already used `x` in tmpfiles, to ensure systemd did not remove
our directories or clean their contents (we really need them to
be left unmodified). However, systemd-tmpfiles lets us use more
than one directive per line, which means we can safely add an R!
(recursive remove on reboot) to these lines to ensure that, if
/tmp is not a tmpfs, systemd-tmpfiles will still remove our
temporary files, ensuring reboots are still accurately detected.
