units: get rid of distro-specific shutdown scripts, replace them by systemd-shutdown invocations
service: rename ValidNoProcess= to RemainAfterExit=
service: rename Type=finish to Type=oneshot and allow multiple ExecStart= lines for oneshot services In contrast to the other service types oneshot services are usually not long lasting and there's not necessarily a single clean main process for them. This change allows multiple ExecStart= lines for this type of services so that the admin/developer doesn't have to arbitrarily pick on of various sequential commands as the "main one".

units: turn shutdown dependencies from Requires into Wants to make things a bit more robust
units: connect shutdown scripts explicitly with the tty, because native units now default to /dev/null stdout otherwise
units: update shipped unit files for DefaultDependencies=
units: tear down sys-kernel-security.automount automount point on shutdown
