[gnome-control-center] gcm_prefs_is_livecd() should be linux-only

[Richard Hughes <rhughes src gnome org>]

commit 3db55d68e106b079b8a28a7d3f16ee40ac1a8fb3
Author: Antoine Jacoutot <ajacoutot gnome org>

    gcm_prefs_is_livecd() should be linux-only
    
    /proc/cmdline only exists on Linux and in this case used to check
    whether we are running out of a LiveCD.
