[gssdp] test: Fix name of lo device

[Jens Georg <jensgeorg src gnome org>]

commit 09d1fd455dedc97e95e44f5af71f6cb5a365f7e9
Author: Jens Georg <mail jensge org>
Date:   Sat Jan 31 13:08:49 2015 +0100

    test: Fix name of lo device
    
    For *BSD, it's lo0. The code now tries to auto-detect the device.
    
    Please note that (tested on FreeBSD and NetBSD) you have to add the route for
    the SSDP multicast group to the lo0 device to make the tests actually work.
