Alan Jenkins d8e5a93382 slice: system.slice should be perpetual like -.mount
`-.mount` is placed in `system.slice`, and hence depends on it.
`-.mount` is always active and can never be stopped.  Therefore the same
should be true of `system.slice`.

Synthesize it as perpetual (unless systemd is running as a user manager).
Notice we also drop `Before=slices.target` as unnecessary.

AFAICS the justification for `perpetual` is to provide extra protection
against unintentionally stopping every single service.  So adding
system.slice to the perpetual units is perfectly consistent.

I don't expect this will (or can) fix any other problem.  And the
`perpetual` protection probably isn't formal enough to spend much time
thinking about.  I've just noticed this a couple of times, as something
that looks strange.

Might be a bit surprising that we have user.slice on-disk but not
system.slice, but I think it's ok. `systemctl status system.slice` will
still point you towards `man systemd.special`.  The only detail is that the
system slice disables `DefaultDependencies`.  If you're worrying about how
system shutdown works when you read `man systemd.slice`, I think it is not
too hard to guess that system.slice might do this:

> Only slice units involved with early boot
> or late system shutdown should disable this option

(Docs are great. I really appreciate the systemd ones).
