tests: zebra_netlink ensure the address is installed

Browse Source 
Ran test under high load and system rejected the sharp
install of routes.  Only reason that that would happen
would be if the address had not been set by the kernel
yet.  The test log files had timestamp precision and the
addition of the sharp routes was under 1/10 of a second
after the address was attempted to be installed.
