[caribou] portability: allow the use of /bin/sh instead of /bin/bash

[Antoine Jacoutot <ajacoutot src gnome org>]

commit c80067412ed9aa434f4bbe2aabed88a21b8cf71f
Author: Antoine Jacoutot <ajacoutot gnome org>
Date:   Sun Jul 8 10:32:44 2012 +0200

    portability: allow the use of /bin/sh instead of /bin/bash
    
    In this case, ${BASH_SOURCE[0]} can be replaced with ${0} which is
    recognized by all bourne shells (bash, sh, ksh).
