[vala] Use Path.build_path instead of using raw string.printf

[Luca Bruno <lucabru src gnome org>]

commit af0aa50cf5cc4f834f550d375a1f6c095d2483ce
Author: Luca Bruno <lucabru src gnome org>
Date:   Mon Sep 5 23:26:45 2011 +0200

    Use Path.build_path instead of using raw string.printf
    
    Fixes a regression introduced by commit 7f7a991aa7689137e166.
    Using Path.build_path prevents having double slash (//) in the path
    which could be interpreted as comments by the C compiler.
    
    Fixes bug 658296.
