[jhbuild] Add support for using GConf schemas installed in the jhbuild prefix

[Frederic Peters <fpeters src gnome org>]

commit 66125d9106294132e1d0c949ec3aecb89549b2c7
Author: Dan Winship <danw gnome org>
Date:   Thu Jun 18 14:55:14 2009 -0400

    Add support for using GConf schemas installed in the jhbuild prefix
    
    Set GCONF_SCHEMA_INSTALL_SOURCE to point into the jhbuild prefix so
    modules will install their schemas there (rather than failing to
    install them into /etc).
    
    Create a GConf source path file that tells GConf to use the data in
    the jhbuild prefix (in addition to the data in the system prefix), and
    point to it with GCONF_DEFAULT_SOURCE_PATH so modules will be read the
    right data (assuming a new enough libgconf).
