[gtksourceview] Fix installed tests to look load the right files

[Paolo Borelli <pborelli src gnome org>]

commit 8780a93009b7c0ec50718b39a089af27ad300c2f
Author: Paolo Borelli <pborelli gnome org>
Date:   Sat Dec 7 21:23:11 2013 +0100

    Fix installed tests to look load the right files
    
    When running from the source checkout we want to setup the tests
    to load the lang and style files from the source data dir, with
    installed tests instead we want to use the ones installed in the
    real XDG dir.
