quagga: delete interface from default table when moved to vrf

Browse Source 
All daemons changed to flag an interface that has been moved to a vrf as DELETED instead of INTERNAL.
When they were flagged as IFINDEX_INTERNAL, ospf, rip, and isis would re-install them in the default
assuming that they were being "pre-defined" before the kernel definitions.
