    Use a temporary, writable directory as $HOME while running tests.
    
    Otherwise, t/overrides.t and t/zz-GtkRecentChooserDialog.t fail in a Debian
    sbuild build environment, with errors such as:
    
      Gtk-CRITICAL **: Unable to create user data directory  '/sbuild-nonexistent/.local/share' for storing 
the recently used files list:  Permission denied  **  
Gtk:ERROR:/tmp/buildd/gtk+3.0-3.8.4/./gtk/gtkrecentmanager.c:622:gtk_recent_manager_set_filename:  assertion 
failed: (priv->filename != NULL)
