[gnome-settings-daemon] main: Remove libsystemd-login specific code

[Bastien Nocera <hadess src gnome org>]

commit f7928b54cccc909ab47bf90b917711f9d195da84
Author: Colin Walters <walters verbum org>

    main: Remove libsystemd-login specific code
    
    After porting both users of the helper code (the power and
    color plugins) to use gnome-session's SessionIsActive property,
    remove the libsystemd-login dependent code.
    
    As originally intended, gnome-settings-daemon requires
    systemd for the power plugin to work at run-time, but does
    not hard depend on libsystemd-login itself at compile-time.
