[gnome-shell/benzea/systemd-user-units: 2/3] data: Update systemd units



commit 2d15a88c5de1e4f9c845d1f3374b4a6198a2874e

    data: Update systemd units
    
    The existing units were never used as the corresponding support was
    never merged into gnome-session.
    
    This commits updates units to be usable with the newer gnome-session
    unit definitions. Also added is appropriate failure/restart logic
    including the ability to disable extensions. Note that extensions will
    only be disabled if a failure happens in the first two minutes after
    login.
