[gtk-doc/wip/hadess/multilib-conflict] scangobj: Make G_MAXINT appear as such on 32-bit

[Bastien Nocera <hadess src gnome org>]

    scangobj: Make G_MAXINT appear as such on 32-bit
    
    Don't overwrite the boundaries of integer properties when they match
    both G_MAXINT and G_MAXLONG. This also fixes a memory leak in the
    generated scanobj code.
    
    Closes: #49
