zebra: Update advertise-svi-ip MACIPs w/ new MAC

When the kernel was sending an RTM_NEWLINK updating the MAC of a known
SVI, Type-2 routes created by advertise-svi-ip were not getting updated
with the new address.
This adds removal of any old Type-2 routes (with old MAC) and creation
of new Type-2 routes (with new MAC) into RTM_NEWLINK processing.

Fixes: #11174
