tests: Modify zebra_rib tests to include some basic route-map tests

New test does this:
a) Ensures that we run the correct number of times given two
`ip protocol X` commands( ie we do not run the route-map application
against all routes, only those affected )
b) Ensure that when we modify the route-map the state ends up sane
this includes making a static route depend on a sharp route that
gets removed from the change of the sharp route-map
c) Ensure that the kernel routes are correct.
