[glib] Fix up the gschema.dtd

[Matthias Clasen <matthiasc src gnome org>]

commit a9f363733ba796b8c2365fc45a616f94bd6463e3

    Fix up the gschema.dtd
    
    This DTD wasn't syntactically correct, and didn't actually
    describe keys correctly. This change makes it a bit too lax,
    but at least it can be used now.
