system: T5505: fix zebra route-map is not removed from FRR

Configuring "set system ip protocol ospf|bgp route-map foo" and commit it
installs the route-map into FRR. Removing the CLI configuration "delete system
ip protocol" does not remove the route-map from FRR - it stays active.

This commit adds the fix and appropriate smoketests extenstion.
