vrf: bgp: T3523: bugfix Kernel route-map deployment
Commit 4f9aa30f ("vrf: bgp: T3523: add route-map support for kernel routes")
added the possibility to also filter BGP routes towards the OS kernel, but the
smoketests failed. Reason was a non working CLI command applied to bgpd.
Thus the VRF route-map and the BGP configuration is now split into two templates,
one to be used for each daemon (zebra and bgpd).
Nevertheless one more bug was found in vyos.frr which currently does not suppoort
calling modify_section() inside a configuration "block". See [1] for more info.
