[glib] various GLib tests: plug memory leaks

commit 29f2ced8eb32d9001da8082c4530f017decb8267
Author: Simon McVittie <simon mcvittie collabora co uk>
Date:   Tue Dec 13 19:01:42 2011 +0000

    These don't really matter, since it's test code, but they do obscure
    real leaks in the library.
    
    Signed-off-by: Simon McVittie <simon mcvittie collabora co uk>
