Remove obsolete battery recall code

It's causing issues

https://bugzilla.redhat.com/show_bug.cgi?id=1028655

and upstream has removed it 

https://git.gnome.org/browse/gnome-settings-daemon/commit/?id=6f1a6debd46cdd279bab8692aa7503e1f7ba954b

The latest update is from the Dell website and dates back from 5 years ago (2009), and the recalls 8 years ago (2006) by the time GNOME 3.12 is released. Even airlines don't check for exploding batteries anymore. https://bugzilla.gnome.org/show_bug.cgi?id=709782
