static: T4883: fix KeyError: 'table'

Commit dafb0da2 ("static: T4883: add a description field for routing tables")
added an iproute2 description table but lacked checking if the key exists.
This has been fixed and also converted to Jinja2 to keep the "common" style
inside the routing protocols. It might feel overengineered indeed.
