Loader: Remove extension initialisation sorting

Extensions could previously declare initialisation dependencies on other
extensions, which would then get nicely sorted by the loader.  We only
had one user for this, GLX, which had one pointless (Composite) and one
possibly useful dependency (DBE).  As DBE is now a built-in, it will
always be sorted by GLX, so we no longer have any users for it.
