Server: disable auto-suspend when on AC power
A recent change to GNOME changed the default for GNOME sessions
(including GDM) to automatically suspend after fifteen minutes, even
when connected to AC. This patch adds an override so that if the
installed system was Fedora Server Edition, it restores the previous
behavior of disabling auto-suspend on AC power.
