zebra: Add uptime to show evpn arp-cache vni .. detail

Browse Source 
Add uptime data to `show evpn arp-cache vni ... detail` command.

Effectively when we create a neighbor entry store the time it
was created.  When we modify the neighbor entry store the time it
was modified.  Display under detail output and json output.

New output:
eva# show evpn arp-cache vni all detail
