[PATCH] Rely on the "Resuming" signal only on a system with systemd

[Imran Haider]

The notify-upower.sh script is only executed on a system with systemd. For
distributions that use logind without a full fledged systemd, this script
will not get executed and so upower would not know that it has resumed.

This change fixes an issue where the system goes to sleep only once and
does not sleep until upowerd is restarted.
