Explicitly sort object interfaces, properties, and signals

Previously we were taking this in order from the dumper, which ends up
being some undefined order from GObject.  Just use Node's cmp to sort
them by name explicitly.

This probably doesn't cover all possible instances of this problem,
but these fixes are right.
