Subject: [PATCH 2/2] tlp-sleep.service: reintroduce

This patch reintroduces tlp-sleep as a systemd unit as opposed to a
systemd system-sleep hook script. This is due to the recommendation by
systemd itself to not use the hook scripts. As per the manual:

> Note that scripts or binaries dropped in /usr/lib/systemd/system-sleep/
> are intended for local use only and should be considered hacks. If
> applications want to react to system suspend/hibernation and resume,
> they should rather use the Inhibitor interface[1].
