[gnome-shell] Call a global variable in our jhbuildrc _libdir not libdir

[Owen Taylor <otaylor src gnome org>]

commit 384b88910a683608ff0cf258a9493b6b5207fcd7
Author: Owen W. Taylor <otaylor fishsoup net>
Date:   Tue Mar 17 16:09:06 2009 -0400

    Call a global variable in our jhbuildrc _libdir not libdir
    
    jhbuild will complain if there are unknown variables not prefixed
    with _ in the jhbuildrc, so rename libdir to _libdir.
