udpgso regression test configures routing and device MTU directly through uAPI (Netlink, ioctl) to do its job. While there is nothing wrong with it, it takes more effort than doing it from shell. Looking forward, we would like to extend the udpgso regression tests to cover the EIO corner case [1], once it gets addressed. That will require a dummy device and device feature manipulation to set it up. Which means more Netlink code. So, in preparation, pull out network configuration into the shell script part of the test, so it is easily extendable in the future. Also, because it now easy to setup routing, add a second local IPv6 address. Because the second address is not managed by the kernel, we can "replace" the corresponding local route with a reduced-MTU one. This unblocks the disabled "ipv6 connected" test case. Add a similar setup for IPv4 for symmetry.
