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 Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Ie2de1fb30091671cbc7c62770903a2e05987f141
