vlib: autogenerate <node> before <last-in-arc> constraints
If an arc declaration includes '.last_in_arc = "some-node"', assume
that folks mean it and add explicit ordering constraints.
Fix the "arp" arc declaration which claimed that the arc ends at
arp-disabled, but the arc really ends at error-drop.
Type: fix
