zebra: handle bridge mac address update in evpn contexts
when running bgp evpn rt5 setup, the Rmac sent in BGP updates
stands for the MAC address of the bridge interface. After
having loaded frr configuration, the Rmac address is not refreshed.
This issue can be easily reproduced by executing some commands:
ip netns exec cust1 ip link set dev br1000 address 2e:ab:45:aa:bb:cc
Actually, the BGP EVPN contexts are kept unchanged.
That commit proposes to fix this by intercepting the mac address
change, and refreshing the vxlan interfaces attached to te bridge
interface that changed its MAC address.
