[latexila] Improve the hacking file

    Improve the hacking file
    
    With the GNU indentation, curly braces around a one-line block is ugly.
    It's better to not add exceptions to well-established conventions. If
    someone wants to contribute to different GNOME modules, it is easier if
    the same conventions are used everywhere.
