Add test cases that verify that when the "onlink" keyword is specified,
both address families (with and without VRF) accept routes with a
gateway address that is reachable via a different interface than the one
specified.

That is, the IPv4 tests were always passing, but the IPv6 ones only pass
after the specified patch.
