[gnome-media/gnome-2-32] Force updating the custom theme dir on change

[Bastien Nocera <hadess src gnome org>]

commit 94d6291aebb68d57ffdbcf7e0a2b1275d1be49dc
Author: Bastien Nocera <hadess hadess net>

    Force updating the custom theme dir on change
    
    When changing only the alert sound, changing the links inside
    the __custom theme will not update the directory's mtime, thus
    not trigger gnome-settings-daemon's sound module to flush
    the sound cache, and the old sound would then be used.
    
    Poke at the __custom theme dir when changing the alert sound
    fixes this.
