Add a test case to verify IPv6 addresses being removed when valid lifetime expires.

To verify whether the kernel removes all IPv6 address from interface
when the valid lifetime expires, as a result, a onProvisioningFailure
event will be triggered if that's an IPv6-only network. Helpful to
reproduce an issue reported by OEM.

Test: atest testKernelDeletesIPv6AddressesOnValidLifetimeExpires --iterations
